Checking on air erasers shows the Paasche kit at $84.00 and one
store in Solana Beach, California, offered the Badger Air Eraser
for about $41.00. As far as I can tell the Badger comes with a
canister of air and some grit. The air compressors at an art
supply house ran from $167.00 to $251.00. The least expensive
air compressor seen was at Harbor Freight for about $80.00.
