If you are going to pick one up right now, REI has a 20% off coupon for members and a $100 gift card (that has to be used during a short period in December). I think this is about the biggest discount on Dometic fridges that I've seen.
I was looking at picking up a CFX3 45, but reading the
CFX3 Mega Thread over at ExPo is making me reconsider. I can't tell if the CFX3 line really is having that many issues, or if it's a classic case of unhappy customers being the loudest.
