need a sand blaster

I am getting a 15 pound portable soda blaster fromr HF for 99 bucks to blast some paint off of plastic...it also works with heavier soda for removing paint from metal...they also have the sand blasters that can use media like glass beads in different grits...Northern Tools is also good but more pricey...also Eastwood Paints has a Hand held gravity feed one that looks pretty good and can shoot many different types of media except soda..
