The choice has become trickier now Phil ... keep in mind however that
these are the exact same basic scope from the same manufacturer, it's only the "trimmings" that vary slightly.
I've pasted the relevant bits from both websites below - Bintel have more "florid" detail but I've removed some of the "filler" and left the basics.
The main diferences I can see is that you get 5 ep's at Andrews, and a Right Angle / Correct Image finderscope for $50 less, Bintel appears to provide the basic "Straight Through" finderscope instead and 3 ep's.
Bintel will also pre-collimate the scope, the alignment of the primary mirror will most definitely move around while on it's way to you up there and will need adjustment again, but the secondary position "up and down" the tube should not move. While all aspects of collimation are skills you can learn to do well, on your own, from the internet (I did) there is some value for you, being so remote, in having that done for you first.
I strongly suggest you also buy a Combination Sighting / Cheshire tube to assist in your own collimation, and perhaps a laser collimator afterwards as well to augment your ability to do a "quick touch up".
The 6mm (from Andrew's) will be hard to use when wearing glasses due to it's very short eye relief (ie distance from lens to eyepiece to obtain a proper image), and the 25mm is almost redundant since they give you a wide angle 32mm as well. That leaves a 9mm, 15mm, and 32mm wide - which is what Bintel provide.
(Interestingly though Andrews state clearly that the "GSO dobs have a 3 year factory backed warranty" while Bintel advertise "You get piece of mind with our comprehensive 2 year guarantee.")
