for the price, yes. however, i would stick with using their hi-hats or rides. the cymbals are beyond thin and may only last a few sessions. the upside to that is after a few sessions, you now have some really trashy sounding cymbals you can use for effects. personally, i would say go down to your local music retailer and try out all their cymbals. start off with the expensive ones for reference (let's face it, can any of us really afford to drop $350 on 1 crash cymbal these days?). once you've found your ideal cymbal, check out the lower-end cymbals. my personal choice would be Paiste's PST-5 series. they sound great and they won't break your budget.
as for the ZXT series, there's a few pro drummers that actually swear by that series. they're a little more than the ZBT, but better sounding and more durable. i've tried those out too. i liked them, but wasn't able to afford a starter kit at the time. my PST-5's do just fine. i'm actually going to be replacing my ZBT's with PST-5's as soon as i can get $250 together for a starter kit (20" ride, 14" hi-hats and another 16" crash).
