I called Toys R Us again, but this time I made sure they understood that be bike works fine but I just don't like it. They said they'll take it back (thank god). The bending on the wheel isn't that bad (I exaggerated a bit on my first post), so I think it can be saved. Thanks a lot for the help guys, I'll update you once I return the Dyna and take the FS wheel to my LBS. Again, thanks a ton - I had no idea the back wheel could be repaired for a fraction of the price of a new one. I guess the best way to learn IS from experience, except I'm lucky that I can return the Dyna and be right back to where I was before buying that POS.
