Yet another post about Rear Sets

I'd like to put rear sets on my '81 KZ750 LTD to give it a better riding position. Are there any sets off another bike that bolt on or are significantly easier to swap over? I like the Tarozzi set, but it's definately at the top of my price range.

I just typed "rear set" into the search box above and got 2862 hits. Have you read them yet?

I've been contemplating this project for 9 months now, I'm pretty sure I've read almost every relevant thread on the subject.
