Hi,
I bought this ETX90 mount for $600 (actually the $600 was for the tripod only, but the gentleman gave me the fork mount and the controller as well).
The plastic declination axes gave me big problem when I tried to adopt it for small telescopes.  Finally I decided to replace the plastic declination axes with aluminium parts.  I replaced the 2 axes, the clutch knobs as well as adding a general purpose cradle to OTAs up to 100mm, or cameras with telephoto lens.
Now I need not wait for BossKwan's TP-1.
