Thanks to all of you.
I had a FASS (pump only) on my '01 for around 70K miles and had no problems with it. In looking at both brands, I was leaning toward going with FASS again for the '07 mainly because of their lifetime warranty and their claim of a 1,000,000 hour motor life. However, if folks are having problems with the warranty being honored, then the Air Dog becomes a better buy.
JJPage: thanks for the contact info on a shop. Boise is a bit over 100 miles from TF and I would like to find a shop closer than that, if possible.
