I have one of the 100lb Harbor Freight blasters - bought it in the mid-90's. It sucked. I ended up replacing the hose and nozzle with professional-grade pieces, and it's much more usable now. At the time, if I'd just bought the "right" stuff the first time vs upgrading the HF stuff, it would have been about $75. I've been using #80 garnet with a 3/32 nozzle and it works great
