A few things on Eclipse. I used to be a Installer of Eclipse.

#1 Eclipse is one of the 2 best brands for headunits on the market the other being Alpine.
#2 Yes if you want the 3yr warranty then it has to be installed at the place you purchased it. Otherwise you get the basic 1 yr warranty. I would Put Eclipse also in the top 3 of decks with the least amount of problems. The Other 2 would be Alpine and Pioneer. JVC, Panisonic, Sony being the 3 worst when you talk about decks with the most problems.
#3 The detachable face thing isnt a big deal if a some wants a radio there gonna take it with a face or without. With an eclipse you have to have the key CD or know who registered it with Eclipse to unlock it.
#4 I have owned 5 Eclipse Decks and never had a problem at all with any of them. My Friend has a 5441 i think is the model # he got it when he got his Cavilier. he got the car in 1996. The thing still works like its bran new!

What was the price he gave you? I can still get discounts on some units. My suggestion if the unit you want is a Current model year i would wait till the new ones come out and then they will be greatly Discounted.

I got my latest Eclipse 5442 brand new for $217. Thats with my discount but i can still get some discounts on some units.
