Just got back from the Spine Doctor. Looks like I'm in for another cervical spine surgery. The worst part of this is I will no longer be able to safely carry around my Tyros 4 for my gigs. No, it is not for sale!. Darn, just sold my S950.

So here is my question to each of you. If you had to lighten your load for gigs which of these options would you consider and why?
Please, no pissing contests here. I need some serious advice.

1. Korg PA900
2. Korg PA600
3. Roland BK-9
4. Roland BK-5
5.. Dan's vArranger - which I do own.

Notice I did not include the Yamaha S950. When I had mine I really was not all that impressed with the overall sound as compared to my Tyros 4 and the audio styles were not all that useful in that they could not be saved to an external device.

Thanks guys in advance for you input.
