Harbor Freight has a 3 hp, 21 gallon 115 psi cast iron vertical air compressor on sale... Item nr: 94667.. Anyone have any info on this compressor... I just got an order for 8 of my pepper mills and that will give me a pretty good chunk of $$ to work with. The compressor is on sale for $129.99 with a super coupon.. it's only on sale through 11/21/2010 so I'll have to go to HF either today or Sunday...since I have a show on Saturday. Is it worth driving 100 miles for??
