I've just bought a s/h ED50 with the 13-40 eyepiece from a well known UK on-line source and I am very pleased with it. From both Birdforum and other birders that I've spoken to it seems that I could squeeze a bit more out of the scope with a WA e/p of either 20x or 27x.
Unfortunately I can't find either on the s/h market. If anyone can help me to locate one I would be very grateful.
