Hi Ket
I have the GSO ED version and its very good. A big advantage is that a Barlow really improves the performance of some of the cheaper Plossl eyepieces - reduces astigmatism by reducing the cone angle - so you could possibly save a bit if you buy some additional EPs. Heartily recommend for a Newtonian scope - I use mine whenever doing visual observing with my GSO EPs. Would be very surprised if it did not just drop into your scope and work.
