The most important thing to look for is the diameter of the aperture. Your resolution is proportional to the diameter of the telescope (absent atmospheric conditions). I would recommend a minimum of 6" in diameter. 8-12" is preferred.

With this in mind, the best telescope you can get for the price is a Dobsonian. Dobsonians are extremely mechanically and optically simple. This makes them long, and bulky. It also makes them cheap. It also makes them rather easy to point. They have a lot of mass and inertia, and a large moment of inertia. This makes them easy to move and point slowly and carefully.

Dobsonians are ideal beginner telescopes. Easy to point, cheap, good resolution.

This is the model I have (8" aperture, $450): https://www.amazon.com/Orion-8945-SkyQuest-Dobsonian-Telesco...

They're also rather easy to construct, if you are of a DIY mind. Here's a 90 minute youtube video on how to build one, with John Dobson himself: https://www.youtube.com/watch?v=snz7JJlSZvw
