Looking to spend 2000 to 3000? Now you tell us, thanks.
For that kind of money you're going to need to decide a few things. Are you looking for an astrophotography setup, or just the best visual setup you can get? If visual, I would go for the largest aperture dob that you can find.
AstroMart often has people selling fantastic dobs for that price well into the double-digit aperture range.
If you're looking for an astrophotography setup, well, that's too long a discussion. You're going to have a hard time getting a high-quality setup for $2-$3k, but you could start out with a decent mount like the Celestron Advanced Series. You could then get a nice apo refractor from Orion (80ED or 100ED) for about that amount. It won't be a great visual scope, but it will do well for astrophotography.
We need more information. BTW,
this is my visual setup, and you can see the Celestron Advanced Series mount on the left. I use it with my computer so that I can monitor remotely, and I also use it for my lighter refractors for simpler astrophotography. The Orion reflector you see there isn't that great a scope, but it's light and it works well enough for quick visual work.
