I had the same learning experience. I started with an oil-less 110v compressor, and the noise drove me nuts in a week. Then I got a 110v twin cylinder single stage 5.5 HP, but that wouldn't keep up, and would only make 125 PSI. I even tried connecting 2 compressors and tanks together for a longer work time before running low on pressure, but it still took forever to recover. I bit the bullet and had a separate breaker box run out to my garage with 220v. I think it cost around $400 or so. I can do most electrical work myself, but I had an electrician do this job. Then I got a 220v 2 stage 5 HP compressor with 80 gallon tank. This thing ROCKS! I run at 175 PSI, but my tank is rated at 200 PSI *working pressure*. I can blast, grind, cut, or polish non-stop now. Save yourself time, money, and aggrivation. Get the big one in the first place. You'll never be sorry.
