I'm looking at picking one up from a friend for $600. Is it worth it? Anything I should know about the older etx branded models? It's an acf with the monitor. Thanks in advance .

The optics are superb. See if it boots up and works, including getting a GPS fix outside. If so, you got a good deal. After that, search the forums for making a firmware reload 2 Gb miniSD card.

Other than the firmware upgrade, the only real difference was badge engineering.

In the very early units, the DEC clutch was not adjustable either. Later models can be tweaked.

No clutches at all on the Lightswitch scopes. They only allow pushbutton slewing.

Not totally true ;)
There are clutches of a sort, but they arent user adjustable by "normal means".
As per the attached piccy, the DEC clutch is actually provided by a preloaded rubber disk, and mine "oozed" under load ( hence how i found it ).
The outer plate effectively does double duty as the DEC axle support in the vertical plane, and the clutch preload in the horizontal direction.
Later versions had a screwable insert added to allow the clutch tension to be adjusted in the shop before sealing it up.

Interesting! But as you said, not a clutch in the sense of the other Meade scope models.

Thanks.
