Lost Studios,
I see that you're in Brooklyn, I lived there for a while, I love Brooklyn. You're not too far from the GC in Carle Place, NY (that's on Long Island between Westbury and Mineola) They usually have many used sets for sale (all in real good shape) Yamaha,Tama, Ludwig, Pearl etc. A 5 piece Pearl export can often be had for just over $300 and under $400.
I've been pricing the Yamaha
Custom Maple Absolute (a top-of-the-line set) and The fellows at LI Drum Center in Plainview can hook me up with a 5 piece shell set used for about $800 (22" kick, 12" and 13" mounted toms, 14" and 16" floor toms, sorry no snare for this set). I know that's more than you wanted to spend but it's well worth it. A used Tama Starclassic (Birch shells) can often be had for well under $1000.( a really excellent set).
Sam Ash has their own line of drums, Sound Percussion, and they are usually not that great, however, they produce a 4 piece gig set with solid maple shells and snare- 18" kick, 12" mounted tom, 14" floor, 14" snare that really sound great (I like it better than the Yamaha gig set, and I love Yamaha drums.) This set is available for $389 brand new. The hardware is also quite good.
