Just want to make a couple of points here.
1. Maks and SCT's have different design characteristics and therefore there is no real better unit. It all depends on what you have in mind for it's use. Maks do have certain optical qualities that I was looking for before buying the C14 for planetary imaging. The price and cool down times certainly had an impact on the purchase. That said small Maks give lovely views of the planets but are very slow for DSO viewing and imaging. SCT's are commercially made at a price and therefore are not as good as they could be. They require flatteners and reducers to work as DSO scopes. The main Strength again for an SCT is planetary imaging over viewing. Although contrast can be an issue with the SCT.
2. Marki, Russian Maks often have collimation screws installed into them. In fact I think it is the Intes version has primary and secondary collimation screws. It is mainly the commercial companies that make maks without collimation screws.
Trevor whatever you choose, I reckon it is worth telling us what you want to use the scope for first, that way you will get a practical answer rather than a theoretical bunch of talk.
