I found a decent price
at Amazon.com and they will ship it for free to your location.
It is also a job that is not too hard for you to do. The hardest part will be getting it up on the roof and there are several threads on the forums to help with that. All you do is put it in place on the gasket, tighten four long bolts as directed in the instructions, hook up the electric, replace the bottom unit inside, and you are done.
Your other post on this subject can be found
here and has some good suggestions.
Good luck.:)

Edit: I see that PPL has an even better price with free shipping
here.
