Hi Alexander,
Without going in to too much detail, the structure relies too heavily on cantilevered elements so it wont hold collimation and will be plagued with vibration. The focal plane will also be flooded with stray light because there is basically no light baffles to speak of. I would be surprised if this telescope performed even as well as a 20"
fwiw) That particular mirror is not well figured, Gary himself acknowledges that the image quality is noticeably breaking down even with a 26mm eyepiece.
He is prepared to sell the optics for $5K
If you add another $2k for refigure & coating,
then add freight and gst, I suppose you are realistically looking at a bit over $8k.... that is still pretty cheap in the scheme of things.
best
