Pros of reflector - zero chromatic aberrations, bigger aperture for a given budget; fast f-ratios possible on a budget;
Cons - collimating the optics from time to time; central obstruction reduces image quality at high power (for f-ratios 5 and under); diffraction spikes on bright objects; mirrors are more likely to collect dust requiring occasional cleaning; may need a coma corrector (f/5 or less) and/or flattener for imaging.
Eyepiece position... depends on what you prefer.
