Nothing wrong with buying an inexpensive gun when you are on a tight budget as long as it's reliable. Most of us have used this stepping stone somewhere along the way and years down the road we still have dream guns to lust after, just more expensive ones. A true gun nut is always looking forward to the next one. Yes, you can add Huglu ( basically the same as CZ) to the list, and those inexpensive doubles by Savage, Stevens, Mossberg will meet your requirements as well. With a $600-$800 budget this will be your best bet, used Berettas, Brownings, etc are very rare under $1000 these days unless with fixed chokes or really beat up/worn out. Get to know the sport, find your limits and aspire to that much better gun that will solve all your problems. At 100 rounds or so per month all but the very bottom of the barrel should give you lots of fun and last long enough to point you towards your inevitable upgrade.
