Trade two K5's for two K5m's?

Hi folks,

I'm running into space problems in my studio, and I'm thinking of 
trading my two k5 keyboards for K5m's if there are any takers. The 
backlights are not working on either K5. Middle C is not playing on one 
of them also, I'm going to try to fix that this week. My preference 
would be if someone is in the San Francisco Bay Area that a trade could 
be made in person instead of via UPS. I'm also thinking about doing the 
same with my two K3 keyboards, if I can find someone with some K3m's who 
want to trade.
