How and where is it bent, post a picture. I fixed a bent frame problem on my LT-R by cutting off the a-arm mount and moving it out so it would line up with the other mounts and straighten my a-arm back out. Alot of things can be fixed by cutting and welding. I realize this isn't an option for everyone, but if you have the recources, or know someone who can fab metal, you might be able to get out of this one a little cheaper than you think.
