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.
