My $.02 worth...
As someone else suggested, make sure you get an oil lubed compressor. No question about it. Don, your new one looks a lot like mine (and thousands of others).
You will need Teflon tape and a few fittings. Of course a tire chuck for non-aviation uses. A blow-off attachment is nice to have too. I wouldn't go hog wild buying accessories right off the bat though, especially if you have a Lows/Home Depot/Harbor Freight/Northern Tool close by.
If I were starting over from scratch, I'd get a retractable hose reel for the cars, bikes, snow blower and motorcycle and mount it on the wall at the front of the garage.
I got a
RapidAir kit from Northern Tool (available form other places as well) and plumbed a couple of air outlets in my garage. I highly recommend it. In fact I'm adding a third air outlet closer to the bench to feed:
the
lightweight air hose and manifold kit from Cleaveland Tools, one of the better tool decisions I've made. I mounted the manifold to the front of the workbench and use the very light, flexible hoses for most of the work I do. I picked up a $15 harbor Freight regulator to feed it. I usually keep the main supply set at 90 PSI, and the little hoses run 40 PSI. You'll want to order a few extra miniature plugs, because I haven't found anyone else that sells them - certainly no one in town.
I just had 220 run out to the garage, a Christmas present from my wife. My compressor can be converted to 220, as can a lot if not most of the belt driven compressors. When I opened up the wiring box to do the switch, I found one of the wires flopping around loose -- they had MISSED the wire when they crimped on a connector! So much for QC. I guess it's been mostly running on half the motor windings since I got it. You might want to go over yours and see if they missed anything - wiring, fittings, etc. I'm glad it didn't destroy anything.
