Innovation is nice but between it's size, the amp draw & the price I personally don't see it as the answer.... The smaller unit won't provide enough cooling, the large unit is $1500.00 just for the compressor.. You still need the condenser, evaporator, controls, ducts, hoses.... So figure $2500 gets you A/C but now you need an Alternator upgrade and some minor wiring upgrades... The compressor draws 25 amps, the blower typically draws another 6-10 amps..
A Sanden with brackets will set you back, $250ish, so for 1200 or so you can go the conventional route.. Personally my car was factory A/C so I used most of the stock stuff so it cost me around $350 with a Sanden, the brackets, hoses, R134 everything...
