Sector 9 makes a decent board for around $90-200. I have one that got ran over by some old lady in a Cadillac when it rolled under her car, it just bounced up and hit her undercarriage when her front and back tires went over it, and I'm still using it 5 years later. I haven't done much sliding on mine (I never bothered to get or make the appropriate gloves for it), except for the occasional time I've actually drifted from taking a corner too fast (15-20ish mph).
Something I'd like to get into next would be Freeboarding (it's more like snowboarding, look it up on YouTube), but I haven't checked recently for prices on those.
