I have coveted both of these scopes over the years and am hoping to finally own one.
First choice is the Celestron C5, ideally (but not necessarily) the white tube with Starbright coatings. Don't need the fork mount but will consider it if you have one.
I'm aware that the optical quality was variable so it must be a GOOD ONE! 
The other contender is an Intes Micro M500. Should be higher optical quality than the C5 but heavier, hence this is second choice. Either or both would be good though!
Obviously either of these scopes will be somewhat old so I'll be looking for confirmation of their condition, e.g. mirror coating, smoothness of focuser, etc. Age isn't a barrier, however, as my excellent C8 is from the early '90s.
If you have one of these and are interested in selling please send me a PM.
