Hi there
I'll take a punt and say that you will get alot of replies pointing you towards something like a 12" Dob (be it a GSO, Skywatcher collapsible or a Lightbridge).
Haven't checked prices but I'd say one of these would set you back around $1,200.00 then you have a healthy $800 to spend on some nice eyepieces, collimating tools, light shroud if you go a truss, etc
Going from a 90mm to a 300mm (12") will be a BIG difference
Hope that helps..
