harbor freight in pleasant hill has some cheep ones?! there tools are cheep buy they have a year warrantee, a buddy of mine and i got a set of ratchet wrenches there, the 8mm on my friends set broke. brought it back they gave him a new set? its a possibility. sand blaster is cool as long as you have a big air compresser. i've been debating getting one to see how well they work?
