I have both the GSO 2" 2x barlow and a Teleview 2" 4X powermate.
The powermate is by far better in design and performance but the GSO barlow is a lot better than some of the units around today as far as barlows go.
I use the poermate both visually and photographicaly but only use the barlow visually.
It cheap and well worth the mony and performs well.
have a looky at the review section on EP for a little trick you can do with the GSO barlow.
