Little difference between the E80 and the G70 to warrant a 76 E (I don't think they've ever had a 76 E ever) and a speaker'ed 76 would kind of get even more than I (weightlifter that I am - not! ) would be willing to tote... I am also still not a fan of speaker'ed arrangers anyway. I've got nearfields at home and a PA at work.

The 76 E60 is still quite the sleeper... pretty good value for money with a 'pro' action. And honestly, I think that Roland's dealer miscues had more to it being a non-contender than anything in the sound or OS. For what you can pick them up for (price AND weight!) they still seem like a good deal. I am sure that with Yamaha's name and marketing prowess, something in the E60's size and price range would do better than Roland...

To be honest, I think that Roland's E series more fits the 'home' designation than the PSR's and Tyros's ... Home users don't need portability, but they DO need speakers. The T3 without speakers definitely seems more 'pro' and the portability of the PSR's seems also to be aimed at someone moving it a lot...

I am not sure WHAT Roland would have to include on a new G series for me to upgrade after only four years or so. The Chord Sequencer... certainly. Guitars like Yamaha's Mega-voice ones? Possibly. MP3 player... pass Synced audio loop player ...? That's a good one But I don't see it happening.

I've got a feeling that, by the time that Roland get a new G-series out sufficiently advanced for me to need it (not want it! ), WS's will have ironed out a lot of the loop triggering kinks and chord following aspects, and I may have moved on...

Doesn't stop me from hankering after a 76 PSR, though. Just like you, I've got a feeling that, for cocktail and background gigs, a (76 for me ) PSR would be close to the perfect tool...
