If you have a soldering setup and wire-prep tools, why not try fixing it yourself? Depending on the break(s) it might be fairly easy to at least get the ignition coil working again, maybe all of them. If not, I'm pretty sure Ricky Stator can hook you up, maybe better than new:
http://www.rickystator.com/page/rewindsI've never really looked for MT125 stators on eBay so I don't know how often they appear there, but I do see MR175 stators (which use the same ignition coil, a smaller lighting coil, and no charging coil) now and then. There's no source of aftermarket stator coils that I know of, only points.
