They are a bit higher priced and they dont have all the "ooooh features" like the swimming dolphins and all that other junk but they have got the best sound quality because thats where they put their time. They have the best parts available in them and superior sound reproduction. But you can get into an Eclipse unit for around 199.00. We had the Eclipse54410 for 199.00 installed. And Eclipse units have a 3 year warranty if installed by an authorized dealer which replaces the radio with another one if it is stolen in the 1st year. They have ESN which you program a "key" cd to your radio. If the power is disconnected then you need to have that disc to get it back working. So if someone stole it they couldnt use it without taking it to an Eclipse dealer and having them call technical support, which in return will look to see if the unit has been reported stolen and who it is registered to. If it doesnt match up they get their infa and have you send it in"for recoding" but actually the begin prosicuting the theif. And they prosicute 100% of the cases. Makes it worth the xtra $.
