What's the prices for cheap skateboards or skateboard parts

Around $125 for a complete set up.. But can get more expensive depending on what you get

Pre-made completes range from $60-110 custom completes are $120 and up but you save 10% on custom made skateboards

I would shoot for $125+ definitely if you're doing it yourself. Mini-Logo decks are only $30, Bones wheels are $20 for example. Depends on what you're looking at or looking for. Their shop brand parts are pretty inexpensive though (like $10 a piece trucks) and premade setups start around $60 (Fishbone brand one) and go up to $100.
