Absolutely. Eclipse is top-notch. I've actually never seen anyone run an "RCA" deck, so I don't know how that made it up there before Eclipse
The difference between Eclipse and most of today's HU is that Eclipse still makes their decks to please all the SQ enthusiasts, and still has the special features that all the other users use, and do it at a reasonable price. Where-as, Alpine will charge you hundreds of dollars for their HU and you still have to buy every single feature add-on (imprint, blue-tooth, time-alignment, sat radio, iPod connectivity).
