With price on the side, which is the better choice?

Did you mean the MK67 (Crayford)? or the MK66 (moving primary)?

Hmmmm...

If you meant the MK66, then...:

Pick the one you feel is more aesthetically attractive (if you have a preference).

Pick one based on the finderscope. The Intes includes an illuminator port. Not sure if the Alter does. Alter's may be worse, optically (but hey, it's a finder).

The Alter includes Vixen-Synta mount rail. MK66 does not.

The Alter also includes an 18mm Erfle, 0.6X reducer/corrector (or a 2.4X barlow -- not sure if this is a dealer-specified option, or who includes what), and a 2-inch star diagonal.

Flip a coin.

Optically? No discernible difference at the eyepiece, given equivalent correction.

Ignore the wall "baffles" in the Alter. They add no optical advantage.

If you meant the MK67, then...:

The Alter is more versatile -- much better able to accomodate astrophotograpy.

Hope I didn't confuse the issue! :-)

Best wishes.
