lots of small inflators w standard Schrader chuck out there, here's one
Husky Electric Air Tire Pump 120V Inflator Sport Auto Bike Car Truck Compressor by Husky
when I needed one I went to a Sears auto center retail shop. it's a Craftsman. swapped a cpl tires last night. pumped them up in less than a minute each. the gauge is accurate. it's small so I can use it in my basement or on the patio.
this looks like the unit I got
this listing too
looks like Home Depot carries a similar looking unit
looks like someone has one on ebay
personally I have no need for a big "compressor"

plugs in the wall. it came w/ some attachments but I liked a Schrader chuck from a previous pump, so I spliced it in
Home Depot has a variety of pneumatic bits & pieces if you ever need to adapt something
good luck
