Thanks for all the advice, I've got to say I'm real torn on this one.
i've read lots of opinions both ways on the size issue, and I've even measured my hand, but I just don't know.
Ebays cheapest second hand isn't any better than amazon brand new, which isn't cheap, and although it looks like the wireless version might be a better fit, twice the price is a lot of cash.

I'll hold off I think for now, I'm planning on whole new pc come June so we'll see then, if there is any cash left over in the slush fund.
