also from andrews commnications is the GS680 dobsonian reflector which will show you 10x as much as the scopes you have picked... my sugestion is that unless space or transportation is a problem then the GS680 8 inch dob is the way to go
the bigger the telescopes aperture in these reflectors the better. the ones you are looking at have 135mm and 127mm aperture. the scope i sugest has 200mm.
but how rude of me!!! i havent even welcomed you to the forum yet!!!
welcome aboard!
heres a pic of the gs680.
