If you intend to get a barlow, I bought the GS 2" 2x barlow. $79 I think it was from Andrews.
The advantage of the 2" barlow is it will take 1.25" & 2" EP's. I have heard several people say in here that they wished they had bought the 2" barlow instead of the 1.25" because when they eventually bought 2" EP's they could'nt barlow them.
And if you ever end up with a 30mm GS 2" SuperView, the barlow gets rid of the abberations around the edges!
