Great response from Allan
The CPC1100 will tolerate a lot of eyepieces, and you don't need a huge budget for it. Trying is always good, before you plump your hard earned down.
As Allan says, unless you regularly get excellent conditions where you observe from, stick to around 9/10/11mm for maximum magnification. I'd suggest a mid-range around 18-24mm for globs and other objects of similar size, and then for DSO...it depends where you view from. I use a 30mm and a 40mm from a dark site, but if you observe from suburbia then the 30mm will likely serve you better (with 40 may show you too much sky glow).
