The battery is the best idea for the current needed. Here is what you are going to find with most any inverter (at least the ones I've found so far) Note the disclaimer.http://www.powerstream.com/dc6-12.htm
If you did the cycling clutch rather than constant on, then just about any aftermarket unit--even time period appearance hang ons such as those sold by Vintage or Classic air would work nicely and be lots less work.
As far as constant on vs cycling, that seems to be more dependent on the parts you use behind the compressor (valve types, vir vs dryer and poa, etc) and you can hide most of that and both types seem readily available.
The cycling compressor type with the inverter you mentioned (which looks like one SERIOUS unit) would be the most electrically energy efficient and wouldn't require a combo battery, and would likely give the alternator a chance to charge the system in between cycles. The only down side is the $300 inverter price.
I fired off an email on the other one posted (5a) and asked if the higher rated 5a neg ground inverter could be used in a pos ground setup if it was isolated to prevent shorts. If so, i'd take a gamble on the one for $99 (i could use it for a radio in the packard glove box anyway) and test it with the compressor i have. The higher rated one, well, it'd have to be a good month at work to throw $375 at a test.
