Dobsonian Telescopes have been known for their ease of use, lesser complexity and overall economy. They're cheaper than their counterparts - refractive telescopes. I'd recommend a telescope that's reflective, mostly because it's cheaper. If you're into astrophotography you could simply add an equatorial mount and you're good to go. I'd suggest you to look into Celestron, SkyWatcher, Orion and Meade telescops.
