I've never really looked at Eclipses, what are the prices like on those? I did a quick search and can't find anything.
From a thread I put on Sound domain a few months ago:
3404 $179(no mp3), 2 sets/rcas, no motorized face
3414 $199(mp3) 2 sets of rcas/no motorized face
3424 $249(mp3) 2(maybe 3) sets of rcas/cd changer control, and remote
3434 $299(mp3), 3 sets of rcas, motorized face
5444 not sure on price(3 sets of rcas, mp3) $449
8053 Still a "new model" for 04...$549
8454 $599 (8 volt, mp3, deck power, NOT BALANCED)
The 3403 and 8053 do not play mp3s(well, the 8053 will play them if you buy the separate eclipse commander advance piece). Other than those 2, all others read mp3 discs.
You can call 800-55-eclipse, and you will be automatically connected to your nearest dealer.
