Hmmm. Well if they knocked say $400 off the RTV 4040 price I could see this being worth it, because these things become obsolete in 2-3 years anyway. This all depends on the monthly fee, of course.
At least an RTV 4000 would be a relatively sure thing, in that I'd be spending $700 now but I wouldn't have to worry about the subscription fees. Plus, for some reason, I predict that Sonic Blue will be at least partially caving in to some of the litigation that's currently aimed at them in these new models.
Decisions, decisions.. I bought both my Empegs at exactly the wrong time, why not make it three in a row?
