Generally speaking refractor scopes are more hardy than reflector scope optics. They are also smaller so better for portable situations. Neither take well to rough treatment so whatever you end up with, a well cushioned travel case is the minimum for protecting them during travel.
Your questions can be better answered on a specialist forum like http://www.iceinspace.com.au They are a friendly bunch and I'm sure they can help suggest a suitable device for your needs.
