A few points.
Collimating a f5 scope isnt difficult. Owning a newtonian you will need to learn collimation anyway. I dont see this is an issue. When you order your scope, ask for a cheshire collimating tool as well , you will need it.
You dont want the 32mm 2 inch eyepiece, its a shocker at f5, and hardly much better at f6 for abberations in the outer field. A much better option is the GS 30mm superview.
The Andrews plossls are bottom of the range, if the Bintel supllied plossls are Guan Sheng, they should be better.
Considering you have 1G to spend, go for the 10 then you wont be wondering what your missing with the 8
