the atwood 750 that most of the sac manufacturers use is at walmart for 23.00. you just need to go to the hardware store and get a little bit of hose and hose fittings. the hardware store guy will get you hooked up and a cigarette light plug at radioshack and they will tell you how to do it also. use heat shrink butt connectors. do not be antimidated. it is very very easy and about 35.00 or less total. drop me an email if you need any help.
