Rock Band Wii gathering dust?

I'm heading up to Williamstown, MA for six weeks and staying in a large dormitory style house. When I was up there last, someone had brought up Rock Band, and it made the long nights bearable. I thought I'd take my Wii up (have to leave the PS3 at home as the media extender for the wife), and discovered Rock Band 2 Wii with instruments is approx $200 online. I can't bring myself to pay that much for it.

Is there any kind Goodjer who may have a Rock Band Wii set gathering dusk in their closet and be willing to loan it out for a few weeks? I pay all the shipping costs.
