Thanks folks. I suppose I am a die hard as well; I've been carting two keyboards around ever since since I've possessed two keyboards.

And the deciding factor is clearly going to be weight versus function. And at present, as the bones creak slightly more on a daily basis, unless I find a total killer reason not to, then I'm drifting towards the 3k + (carefully setup) MU80 solution. It may even force me to be organised for once!

And I suppose if after a while I find I really hanker for two sets of keys I could always shift the 2k and the 3k about, but two "nearly the same" seems a rather less appealing than two "definately different" even though I know the sounds could be drastically different. I'd still have to organise the MU80 somewhat because I still wouldn't have sufficient "remote" control out of a PSR.

I'm going to absolutely understand that I really can setup the MU80 as envisaged (Anyone got a good editor, by the way?) and I'll get keep you posted.

Thanks again.
