Why are they more expensive than SCT's of the same aperture??? Central Obstruction is pretty much the same for both.

Maks are usually used in the smaller sizes, where they can be competitive in cost. See:
http://en.wikipedia.org/wiki/Maksutov-Cassegrain_telescope
The chief disadvantage of the Maksutov design is that it does not scale up well to large apertures (>250mm/10 inches), since the corrector plate rapidly becomes prohibitively large, heavy and expensive as the aperture increases. However, specialist manufacturers do create models beyond 14 inches in aperture.
