Hey Andy!
to the forum.
How did you hear about us?
I can't add too much more to what the guys have already stated - I bought mine from Bintel, others have bought there's from Andrews. But they are exactly the same. Oh and my scope is exactly that model.
Bintel charge a bit more to take it out of the boxes, check everything, collimate and center-spot (if necessary, most are already done these days). So really it's up to you.
The dobs are great value for money, and there's so much you can do to them. I've done a few additions and modifications you can check out on my
projects page.
Also, are you into (or are you likely to want to be into) astrophotography? It is possible to do
astrophotography with a dob, but if astrophotography is high on your list of requirements, then as much as it pains me, i'd recommend something with buzzing, whirring and clicking noises
Good luck and come back often!
