Hey...I have a brand-new condition Yamaha PSR-275 (I bought it new about a month ago, took it out of the box to check it out (played it for an hour) and put it back in the box. My idea was to sell it on ebay and make a few bucks but I am a terrible sellsman and I didn't get any bids (I had the bid starting out at my cost - $102)...It had been marked down twice at the store (I think it was originally around $149 and was selling for $94)...It is very similar to the PSR-273 (so close that the owner's manual has both model names on the cover) which, last time I checked, was selling for $156 at Musician's Friend. It came with an adapter also. With tax I have $102 invested in it and that is what I would sell it for, plus shipping.
i'm selling an alesis qs6.2 for 400 (that includes shipping). If thats to high make me an offer, but I'm in no hurry to sell, so it can't be much less than that.
