Looking for Ideas for a Replacement Wheel

I noticed a few days ago my rear wheel had some wobble to it. It's pretty new and I've done some hard riding, so I thought it was time to take it in for its first tune-up, thinking they would just true the wheel while it was in there. Well, one of the mechanics called me the next day saying it was bent beyond truing, and I should get a new wheel. It's not bad enough to where I can't ride, but I will need a replacement sooner or later.
Anyway, the options he gave me were #1) I can get a bontrager (can't remember which one), which retails for $80. He said it's designed for rim brakes making it heavier than my current ones, but it can accept discs. Option #2) I can go with a replacement of the stock wheel, which is a Specialized Alex, for $60. In his opinion, the Alex is better because it's lighter, yet still strong enough for the kind of riding I do. I didn't bend the wheel riding, most likely. I did a really dumb thing and tried to fit two bikes into the back of a Honda Civic, with mine on the bottom. Needless to say, that won't happen again.
Anybody have any different suggestions? If not, what do you think of the two above? Sorry I don't have the name of the Bontrager. I don't want to drop too much money, I'd say $80 at the most. But, if there are other, better wheels out there for around that price, I'd consider going with them. I mostly do XC style singletrack, since there's nothing in the way of aggressive terrain where I live.
