I dropped my bike in to the LBS yesterday for a bit of TLC. My back wheel was no longer true, and a few other niggles needed sorting out. I think the wheel un-trueing happened when I took one of the speed-bumps on campus a little too fast (they are badly designed square ones for some strange reason). Knocked the pannier off my bike and broke the attachment hinge on it so must have given the wheel quite a knock.

Anyway.....talked to the shop this morning and apparently I need a new rear wheel. There are cracks in the rim, and the hub is pitted. Don't recall what the name of the wheel they suggested was, but it was £80 which sounds very pricey when I may be out of a job soon. The wheel they suggested was apparently an upgrade from the ones I currently have (came with the bike, Specialized Tricross Sport 2005). I told them I'd think about it.....but I have no idea what thinking I could be doing. I know nothing about wheels. What should I be looking for? What's the difference between more pricey and less pricey and how do I decide what is pricey enough for me?
