Less than that.
Get your tape, drop cloths, and such from home depot
Buy your gun from harborfreight (mine was $10, and add $5 for the filter/regulator) - or rent one from a local auto-body supply shop
Order your paint online. I bought a single-stage eurethane kit with 1-gal, hardner, reducer, mix-sticks, filters for $120
Suggest a decent 3M mask from a good place like that as well.
www.tcpglobal.com has some great prices, colors, and paint kits like the one I mentioned above.
