Another vote for the Marlin brand.
I have the model 60 semi-auto and the model 39a lever action. Both are great shooters. I highly recommend the model 60/model 795 [diff is basically tube fed magazine vs detachable magazine], as they should cost new under $300 easily, after fees/taxes. And used they can be had closer to $100. Great knock-about guns!
CZs are very nice. They cost more in the area of a new Model 39A lever action though.
If you goal is a low-cost plinker for cheap recreational shooting, I'd say you should check out the Marlin and the Ruger 10/22. Both have good reputations and won't break the bank.
Love is not the dying moan of a distant violin. Its the triumphant twang of a bedspring.
