For a slow scope I'd pick a quality prism, like the Zeiss T2 from Baader. A shoot-out on CN a while back showed that the prisms have less scatter with high-mag, high contrast views (like planets).

Prisms also have the advantage that they seal the OTA, so you don't introduce tube currents when inserting a warm eyepiece (out of your pocket).
