Hi Sean,
not sure if it's too late for your sale. perhaps i'm not the best to give advice as i'm the kind of person to do lots and lots of research.. and then some more.. and maybe a bit more before i even consider purchasing stuff like this. from what i've read though, you should really consider getting at least an 8 inch dobsonian as they aren't too expensive in the scheme of things. with the 6 inch, you'd probably find yourself wanting to upgrade pretty quickly and it's probably quite difficult to shift something like that on the second hand market. also consider your budget. I'm pretty bad in this respect, in that I'll set a budget and then somehow go over 50% or more if an opportunity arises to get something better at a good price point.
please also keep in mind that I currently don't own a telescope.. in the research phase

my mount is just sitting there with nothing to power it and nothing to put on top of it heh.
