Hi Suzy .... I think that $400 for 10" Dob is great as long as scope and mirror OK. As jjj says, they can be a bit awkward, but think didnt jjj had a Dob??? Dobs are easy as you just pick up the tube and plonk it in the mount ... only 2 bits basically. With equatorials, you have to position it on a tripod, and that would be tricky and very awkward.
If you are still in 2 minds, go and have a look at it, and see if its too heavy for you. Usually you dont have to carry too far - house to car, and when observing out with a group, your car is next to you.
At home I have mine set up on Bunnings trolley, so just wheel it in and out.
If you think you are going to stay with this great hobby, go and have a look at it - you can always sell the little Dob if pressed for $$.
Wish I was down there, I would go with you
Good luck!!
PS ... Buy it!!
