So last year I picked up a Miyata 912 locally. It was in decent but not great shape. After a couple of rides I found out the pedal threads on the drive side crank were stripped. Didn't have a ton of money to spend so I had the LBS put on an el cheapo crank (it actually had the plastic tooth protector ring on it. It fell off...) so I could at least ride it.

So now I have some money to spend on the bike and am planning to put on new tires, cables, seat and replace that eyesore crank. I am willing to spend $150 or so on a crank and don't care if its new or an Ebay find. Its all Shimano now but the crank that was on it was campy. Stick with Shimano? Campy? Sram? IF so, am I better off with a new lower quality component or used but higher end? Or does it not really mater in the long run.

The brake adjusters are stripped also but they still work, so in the future I'll be replacing those as well. I will want to make sure it matches the new crank brand-wise, I'm just anal about stuff like that though I'm sure it doesn't matter. So that is a consideration as well

So, with that in mind I'll take any advice your willing to give.
