That flea market really never has anything, so I never go there anymore, Play N Trade in Lafayette, near the Brother's Department store, is pretty much the only place I check out now, I actually clean up there when I get the chance (mainly NES so far, but a few Gameboy carts), there's a few collector's that go there, so I have competition. Their retro selection isn't huge, but so far I've found some games I've always wanted to own. Thankfully the longer they have been open, the better their selection has become, I always see something I like, but can't get everything because I'm on a budget, their Genesis collection for now still isn't good, their SNES selection is improving, their Gameboy selection is getting good as well. The guys even had a few hucards, don't own a TG-16, so no competition there (some guy cleaned them out of all but Keith Courage). The guys there love me as I've given them lots of cash so far, but right now they know me as the Mega Man guy.
I even forgot about my budget one time, felt like I hit the jackpot, picked up 12 NES games, and 2 Gameboy games (they sold me Tetris GB for $7.99, one of 2 gripes so far, the other being a $19.99 Mike Tyson's Punchout which I passed on), my total came damned near $100 and my eyes got wide when I realized what I had done. Said to hell with it and just bought the stack I had just racked up.
Not close enough to Broussard or New Iberia to check out their Play N Trades, but since they are individually owned, one won't know what the other has.
