I played the SD1 over several long audition sessions, and on separate occasions. Though I appreciated the nice 76 key feel, it's compact dimensions, it's live drum style sync feature, and some nice impressive sounding instrument voices, it overall left me unimpressed, namely because I felt the the bass & rhythm section bass heavy & muddy (unfocused?) sounding, and it lacking in enough swinging jazz styles, with many sounding overly busy to my ears. Navigation with all the identical buttons in straight rows drove me wild too. Even after attempted tweaking . I find the Yamaha OS navigation & Korg PA1XPro sounds & styles more open & transparent (life-like & natural). The BIG thing that turned me away from Ketron (at that time) was Ketron horrible breakdown & repair record. As a PRO musician, I can't afford having the keyboard in the shop all the time. When I auditioned the SD1 & XD9 at my local Ketron dealer, I not only witnessed an SD1 being brought in for repair for the 2nd time in a month, but the XD9 I was auditioning kept locking up when simply selecting another bank/style. I'm waiting for SD2 before giving Ketron another look. In the meantime, the ONLY Ketron dealer I know of within 300 miles of me advised me they no longer carry Ketron because of all the keyboard repair problems they had. Donny, if you switch to Ketron, be prepared for a STEEP and LONG learning curve too. The beauty with the Yamaha Tyros is you can just sit down and start MAKING 'Terrific sounding' MUSIC from the get go, and with Tyros2, people can STOP COMPLAINING that the keys feel cheesy and toy-like any more. Only 61 keys, so what?! It's an auto-accomp arranger for god's sake, and remember, it was you that always made it a POINT that the keyboard's easily transportable size & weight is an all important priority to you because you "gig everyday". That said, it seems to me that your only truly lightweight options now are the: Midjay, SD1, or Tyros2. G70 weighs nearly 50 lbs, and the PA1Xpro is a close 2nd.

Ok, if I haven't said enough already, remember that highly respected SZ musician members, Roel & Dreamer, BOTH owned the SD1, and then after an extended honeymoon period enjoying it, like you with your PSR3000, chose to 'DUMP' (using your words their SD1's, in exchange for the Tyros, and are now upgrading to Tyros2 . . .

as the world turns.
