I'll add my 2.2c inc. GST worth here, although I've only used several GSO eyepieces for one night's observing (last night). The 1.25" 15mm plossl is pretty good. The 2" 40mm plossl is also pretty good. The 1.25" 4mm plossl is well, bad imho. Severe fringing as soon as anything remotely bright is near to it, lacks contrast, very small exit pupil. You end up with a small circle that moves around and it's all you can see anything through, the rest is like just black or internal reflections. The 2x Barlow was OK as well.
Look, for the price, you could do worse, but there is better. I bought a few of the GSOs as they were cheap, and were only intended as starters until I can afford better quality units. I knew that they'd have limitations, and accepted that.
