I am not a pro by an means, but I have recently gotten into amatuer astronomy myself. I bought a Celestron 114 nexstar. Its a 1000mm Focal, and 114 aperature. It does a very nice job for a beginner scope. I paid around 150 from BJ's actually. It came with the full tri-pod, sky align motorized drive, two ep's 25mm and 10mm, and finder scope.
I have since then bought better ep's, filters, and collimation tool. The sky-align feature is very nice for beginners. If your not familar with the motorized driven scopes, they are battery operated and have small on board sky navigation system. My son and I love it. We have seen 3 of Saturns moons, Jupiter and two of its moons, Pleaides, Orion's Nebula Trapizum, and of course the moon in great detail, and other galaxies/nebulas. Its a great hobby to get into,expensive, but what hobby isnt.

For the money you are looking to spend, from what I gather, get a good scope with big aperature, but the ep's make the difference. When I bought the better ep's, huge difference.
