Still researching for the best scope, and I came across the Sky Watcher collapsible scopes...

How well do these stand up to repeated use? I would think that after several assemblies, the tube would begin to sag down on the trusses and it would slowly go out of focus... opinions? Also how well do these hold their collimation compared to other truss-tube dobs? I would think that because the secondary mirror is still more or less fixed in place (not detachable), it would be less mobile and less likely to become out of alignment with with the primary... is this even a concern? I also read that solid tube scopes will still need to be realigned when they are moved...

Also, Telescope.com is offering one of these scopes w/ a 10mm and 25mm "Super" Plossl... are these good EP's to start out with, or are they cheap-o bundle-in's? I understand that they won't be top-line, but "good" would be acceptable...

What are the bases like on the skywatcher dobs compared to others... do they stay in place well?

Last... telescope.com and Sky-Watcher's website contradict each other on weight... Telescope.com claims that this is 69 lbs (!), but the mfg. website claims 22.5 kgs (base + OTA) which is a much more reasonable 50lbs... which is right?
