They also have good imagers as well. The owner, Theo, is also a member here.
Now as far as imagers go, you could opt for a DSLR camera or go for the CCD camera. In the long run, it all depends on how far into imaging you want too go. I would suggest if you want to get serious, to invest in a CCD...although it can pay to work your way up to one by starting your imaging with a DSLR. A Canon 40D would be a good start. You can have them modded by removing the IR/UV filter which will make its red response a lot better than otherwise. That way, you learn the ropes with imaging and image processing before you get into the big time imaging. You can also start off fairly cheaply with a CCD camera. An Orion Starshoot Pro will cost around $2500 at Bintel. It's a OSC (One Shot Colour) camera, which will a bit easier to use in the beginning than a monochrome CCD, especially if you want colour pics. You could also get a QHY8 but that is a $3200 investment. Keep an eye out in the Trade and Classified section and you may pickup one that's cheaper. SBIG cameras are also very good, however they maybe a bit out of your price range unless you pick one up 2nd hand.
I'm heading for Zzzz-land right now, so I'll reply again tomorrow. Someone else might chime in with advice on cameras and other gear in the meantime.
