For visual use and the same price both used scopes
Either a Burgess 91mm triplet or
an Orion 110mm doublet

Myself I would choose a 102mm F/7 ED... 91mm is a bit too small aperturewise, 110mm F/7 is just a bit too big to be Grab and Go...

I saw that 110mm F/7. The claim was no false color on bright objects... I have a hard time believing that. This is 110mm F/7 doublet with ED glass. Since Orion will always boast if it using FPL-53, this is most probably that H-PK-61 which is used in the very similar 102mm F/7s. Since chromatic aberration increases with aperture if the focal ratio is constant and since the 102mm F/7EDs are not color free on bright targets, well, it is pretty clear these are not either.
