Hi Gary
I just took delivery of a LP crayford (11:1) from Andrews ($149) but haven't installed it yet since it involves redrilling and I want to do the mod at the same time as flocking (on order). Can't vouch for the GSO units but the quality seems very good - smooth operation, graduated drawtube, excellent quality finish. The standard one that came with my SW 10" dob was pretty basic. Feel free to PM if you need any other info.
