Some good advice there! I agree that it is better to wait a bit, and that an orthoscopic is probably traditionally the sharpest for planetary work. However, they have a very narrow fov and small eyerelief, so are difficult for eyeglass wearers.
The Orion "edge-one"/ Williams "planetary" and other re-badged "clones" are all very good, and they have 20mm eye-relief with a wider fov than a classical ortho. Long Perng have a line of these at a much lower price (check out Andrews)... I have the 5mm version, and it holds up very well against much higher priced eyepieces.
All the best,
Dean
