HI guys

,
Ok i have a 130mm X 900m reflector on an eq mount and after a while am looking to upgrade to a scope that will serve me for quite a while.
I'm currently borrowing a 10'' solid tube dobsonian and while i can see that it makes everything brighter it is a real pain to collimate.I don't have any collimating tools.
Anyways andrews are having a sale on their sywatcher collapsible dobs cheaper than the solid tube gso are they of equal optical quality? I thoght with the fifty dollars that i save i could buy a chesire for collimating.Just wondering whoever owns one of these could give some sort of review on how they perform and if i should buy one.
I'd love to know what you guys think.
Thanks in advance
