Looking for Smallest 12V DC compressor. For a mobile refridgerator

Dear forum members,

I found the danfoss models BD14F Direct Current Compressor R134a 12_24V DC 50/60Hz
and BD35F Direct Current Compressor R134a, 12-24V DC, 10-45V DC Solar & 100-240V AC 50/60Hz
and also http://www.aspencompressor.com/products/

Are the aspens compressors as good in quality and durability? if this is the case i will most definitely go for the Aspen model. look at this crazy comparison between the aspen model and the market leader (whoever that is) http://www.aspencompressor.com/Downl...M%20AD_F_C.pdf
