Are you looking to spend $1000 on just the drums - or for drums and cymbals?
If you need drums and cymbals about 60-70% of your budget will go towards drums. So, in the $600 range your looking at
Yamaha Stage Custom,
Mapex M series, Pearl Export, Sonar 2001 and I think
Tama Swingstar and Pacific. That leaves about $300 which will get you a box set of Zildian ZBT,
Sabian B8's of Paiste 505's (with just enough left for taxes).
They are all good kits. I personally like
the Yamaha Stage Custom (Birch/Mahogany). Since they are discontinued (the new Stage Customs will have isolation mounts) the $600 price is a good value - they previously sold for $750.
If you're willing to spend $1000-$1200 on just drums you can move up to Yamaha Beech, Pearl Session, Mapex S series, etc. (big improvement in sound)
I would suggest moving up from the ZBT/B8/505 compromise - plan to spend about $400-$600 for decent cymbals (ride,crash,hats). You'll be much happier with something like Zildian A's or
Sabian AA's or Paiste Signatures
Whatever you buy, good luck!
