Hi Harry,
Welcome to Ice n Space
Is this as good a deal as it looks? YES.
Quote:
First grade 12" (300mm x 1500mm) Dobsonian reflectors with truly outstanding 1/12 surface wave BK7 mirrors and 2" focusers and 2" to 1.25" adaptors.
Resolving power; 0.38 arc second.
Limiting magnitude; 14.9.
Includes a right-angle correct image 8 x 50 finderscope, 2" Crayford style microfocuser with 10:1 fine focusing, a 2" to 1.25" adaptor, fan and premium GSO 9mm, 15mm and 25mm 1.25" Plossl eyepieces!
GSO ASDX Dobsonians now have knurled collimation knobs fitted to the primary mirror cell. This feature allows much easier and more
precise optical alignment.
Large knurled aluminium side knobs adjust tube tension

If you want a good easy to set up scope for visual observing, then this is a good deal (IMHO).
Only question I have is whether you will be comfortable lugging it around, being a 12" FULL tube scope.
Perhaps a bit extra to get a collapsible scope may pay off in the end if it is easier to move about. Or drop back to a 10"SW collapsible (flex dob) for the same price.?
