Basix is a European drum brand, so far as I can tell. Most of their product here in the US appears to be lower-end beginner kits, but they have some birch and bubinga kits in their lineup too. I would imagine that an 18" kick would not necessarily be kid's stuff.
Hey, if it sounds good, the fittings are solid and the price is right, go for it! An 18" kick is a handy thing to have.
when u lowball him for $30...ask if it is a "Zildjian Symbol" brand bass drum ? BUY IT...that is a gigger / home studio dream drum.
