said by capdjq:I, too, use my PS3 as my main DVD Player. My Harmony (520) works excellently with the PS3 adapter, which I purchased for $45 on sale.
My only problem, with Harmony One, is the cost, approx. $225, with tax. The cheaper model is the 650 which can only accomodate 5 devices. The 300 can do 4 devices but only 1 Activity (Watch TV). My PVR remote can do that.
The older models 520 and 550 can accomodate 15 devices and innumerable Activities but Logitech has discontinued them in favor of the much more expensive One.
However, no matter which model you possess all are programmed with the same software and perform the same way. No model does anything more than the other except the Harmony 900 (uses RF technology and costs $350).
I bought mine at futureshop, I paid $165 for the Harmony One and $60 for the adapter. Both were price matches, not sale prices.
The main advantages of the Harmony One over the enormously cheaper 650 (those that actually affect what you can do with it rather than conveniences like batteries or touchscreens) are primarily the device support (I've got six in it now, a seventh coming) and the support for sequences (the 650 doesn't, the One does). Most of the other differences are convenience things. For example, you can't reorder or rename custom activities on the 650, can't assign custom icons to TV channels, can't use a charging cable, etc. These kinds of things don't prevent you from doing anything (like the device number limit or the sequence support).
I was tempted to get the 900 just for the extra four bluray buttons despite the higher cost (which I would have pricematched down to 290 or so), but the deal killer was that the 900 doesn't support sequences, making it surprisingly a worse and less capable product than the much cheaper One.
