CZ made the original select fire, full auto version from about 1958 to 1984. CZ hasn't made one since. Though many are still being rocked by the Czechs (though being replaced by the CZ Bren 805 rifle), Slovaks and a number of other countries. The Czechs gave a number to Iraqi/Afghani soldiers during the last decade.
Even when CZ sold the current civilian rifles available. They neither imported or made them. That was done by Czechpoint. Which imports them, modifies them and sells them. These are all made by Czech Small Arms in the Czech Republic. CZ simply put them in a CZ marked box and sold them.
Besides 7.62x39 varieties. CSA also makes the 58 in 5.56/.223 caliber as well as .222 (which is mainly made for countries where civilians can't own "military caliber" weapons.

They make three barrel length versions. As well as full auto variants for demos/military/police.
--------------------------------
Besides gunbroker and other places. Czechpoint is sold out of everything except for the single stack mag variants and the 7.62x39 pistol.

They don't sell their rifles with the beaver barf because "CSA and them don't have access to good quality furniture anymore". Since the panic ended a few months ago. The barf can be found other places if you want it. Czechpoint has had the 7.62x39 rifles available a few times. But have sold out within a few days. Supposedly a few 5.56/.223 rifles are to be available at the end of Sept. But it's the end of Sept. now.
The one that jdonovan linked to is the single stack mag variety. You don't want that.
Besides Czechpoint the other major supplier of 58s is Century.
Some can be found here and perhaps other places:

The big difference in the Century guns is that the barrels are brand new/made here in the USA. Are slightly longer than the original length barrels (which allows the easy removal of muzzle devices). These barrels are also not chrome lined. (The CSA/Czechpoint guns use original, chrome lined barrels. And since the barrels are (barely) under 16 inches. A permanently attached muzzle extension is tac welded on to the barrel end muzzle threads. If you want some kind of device on the end of the barrel. You must have the extension removed and a device welded in place.
As far as Century goes. These overall have been very good. But they can have the usual Century made issues. So you'd have to check them over carefully.
These guns are around half of what the Czechpont rifles cost. They used to be cheaper. They can be good guns, but again they're front Century. So you have to be careful.
Some data points as compared to the AK family:
All vz. 58 rifles possess a milled receiver; the vast majority of AK-47s utilize stamped sheet metal receivers and are not as rigid as the vz.58 receiver.
Even with the milled receiver it is almost one pound lighter than a stamped AK-47.
The bolt of the vz. 58 stays open after the last round in the magazine has been fired – the shooter immediately knows the firearm is empty and allows for quicker reloads.
The vz. 58 can be reloaded with stripper clips while the magazine is inserted in the rifle.
The vz. 58 has a more natural point of aim and is faster handling.
The safety is more ergonomic making a faster first shot possible with the vz. 58. Unlike the AK safety, the vz. 58 safety can be operated by just a forefinger with the hand remaining on the pistol grip.
vz.58 has no need for an ejection port dust cover as the receiver is completely enclosed. A cover (on the safety lever) must be used on the AK-47 to prevent debris from entering the receiver through the reciprocating charging handle slot.
The ejection port is HUGE. There is no chance of an empty case getting stuck in the action of the vz. 58.
The vz. 58 gas piston can be removed or exchanged without tools.
The alloy magazine of the vz. 58 is half the weight of the steel AK-47 magazine.
The vz. 58 is striker fired unlike the hammer fired AK-47. This reduces the number of parts and possible points of failure.
------------------------------------
I own a couple and love them. It's my favorite rifle. If you end up getting one or just want to know. I can point you to places for mags/accessories/etc.
The regular/same shaped/contoured handguards can heat up very quickly. Even with gloves on. So if you get one. Railed handguards and a forward grip may be advisable.
