ski servicing

I want to start doing my own ski servicing and was wondering if anyone could advise on a tool for sharpening edges. There seems to be a wide range of different tools out there as well as a wide range of prices. 

Have you seen the waxing and edging videos at Jib Tuning? They discuss tools too.

Thanks Robert. Everything I need to know there.

This guy (Scott Hargrave) is really helpful

I have used this firm for sole repair tools.

Jon, at The Piste Office (link above) also does a servicing tutorial. Was a well spent Saturday morning for me.
