I did the same thing. CW wanted $1200 for the Dish 1000 on sale and I talked with a local shop and they got it for me at $1100, but I'm pretty sure they got me for labor.
My first dish lasted 10 months and then the motor jammed in the up position and I had to take it apart to drive home. They sent me another one,good customer service, and paid to have it reinstalled. That one lasted for 15 months and they won't warrantee tthe second one past the warrarnty period for the first one or 24 months from the original purchase price.
I'm thinking about writing to Good Sam about that one. They'll sell me a reman turret for $450 (none in stock tho) or a new turret for $750 or a reman total unit for $850.
