I know there have been so many threads on 'truing a wheel' ect, but it is expensive to do.

My back wheel is bent. When i roll it on the ground it hardly moves, when riding i can easily roll with it but i know the pads are rubbing against some parts of the rim (when the wheel is moving so fast is has little effect). Still i dont want wheel rubbing because i am getting this rubbing vibration from the brakes to my seat post to my seat, and it is really annoying and i know that it is slowing my down just that little bit.

So i have two options. I either leave it, and get my LBS to adjust the brakes so it wont rub, but braking power wont be as good.
Or get the wheel trued for $27.50?

what does everybody think?
