thanks all.

The crankset idea was from a post that explained that it may be cheaper then three new rings, and sure enough there is a deal on an LX hollow crank set for $50 at Jenson's (In the hot deals forum), however these are 9 speed rings and you have to get the BB that matches for another $24, but still good value.

Since I run 7 speed and now understand a bit more about chainline, will stay with the cranks I got and get Nashbar rings.(unless someone tells me quick that they are crap.

Its hard to find 7 speed stuff, which is why the Nashbar rings. I was tempted to take advice that says to just go with 9 speed rings cause they're simply narrower but should still hold the wider chains.

Thanks for the other advice, though I did figger out I have 68 mm English threads and a 118 mm spindle.
