To add to the comments above, an 8" from a dark sky will be better than a 10" from suburban skies; if you'll mostly be observing from the backyard the 10" is the one to strive for - if you have a flat run from storage to observing spot the scope is easy to move on a trolley. The optical tube is around 30 pounds and not hard to lift or carry if you have no bad joints, etc.
In the smaller scope sizes (up to 10") the solid tube is more convenient than mucking around with trusses and shrouds - easier to keep the interior of the scope clean - but opinions will differ here.
