The best image quality Newtonian reflector because it has a small central obstruction, among others.
The biggest advantage of reflectors (The Schmidt-Cassegrain, aka SCT is by far the most popular retro-reflector telescope) is its compact size makes them easy to transport and allows the use of a small hill, as compared to one equatorial mount Newton.
This is done mainly by bending the light path in the tube. But it also means a complex machine with precision multi-glass surfaces produced. The greater complexity also increases the cost, so that the SCT, size for size, one of the most expensive telescope out there. In addition, most repairs require that the application will be sent to the manufacturer for repair.
The reflector tube with its open design is nothing you can not fix, even in the event of an accident.
When you talk about his first telescope, I suggest, a Dobsonian telescope in 6 "to 8" range from a company like Orion have sold well equiing very good price and is behind the team 100%. (Incidentally, a "Dobson" is actually a Newtonian reflector telescope mounted on a single assembly by John Dobson popular)
A telescope is a precision optical instrument, this is not the place to try to save a dollar. There are a lot of junk telescopes in places such as eBay, Amazon, department stores, etc. It takes a lot of experience to separate the few good ones are found selling to under all the garbage.
But you have the most important piece of advice anyone can get to you. Visit a "Star Party" in the astronomy club in your area. They are free and you can walk through many areas. You will be more than an hour to get one of those games you read about him in a month.

The cat is just a special form of the mirror, like Newton, Cassegrain, Schmidt-Cass, etc. Do what works best, depending on usage. For most people, save money and receive a Newtonian or Schmidt-Cass, if you want.
A Newtonian reflector generally better than a reflector of the same size, if they gather the light and the ability to define, but not much. Newtonian reflectors are generally more profitable, especially if they are on Dobsonian mounts.
However catadioptric generally have larger focal lengths, which has its advantages, and because the secondary mirror is connected by a spider vein, there are no diffraction peaks, in the stars. They are also more compact and mirrors, the easier to mass produce.
When it comes to astrophotography, desktop, catadioptric cheaper by the end of May, because most are on the market today, mass-produced with computer functions and fit to use a fork. Newtonian reflectors are typically German mounts, the fast expensive, especially the computer, or Dobsonian mount, which are used for astrophotography, where can an equatorial platform and install special encoders.
Astronchemistry is a hobby of compensation.
A cat is a reflector of various kinds. The best telescope for the money would be Dobson.

For the same money to get a reflector with an aperture much larger than retro. But if you have a local astronomy club, because you need to know the type best suits your purpose.
