The Coronet is my favourite of these; it is like a small bodies LP Junior and, in my opinion, more "lively" than a Junior.
The Wilshire is very cool too. The two Crestwoods I've played haven't been that great, although obviously I could have only seen a couple of bad examples.
I prefer the wider necked pre-1964/5 models from a neck profile perspective, although your views on this may differ.
I'm not a huge fan of the vibrato tail piece.
Main things to watch out for:
As with all Gibsons headstock breaks/ repairs. Look out for any refinishing around the back of the headstock.
It's rare to find an Epiphone/ Gibson refin, however clear overspray is not uncommon.
On guitar with a front pickup (eg Wilshire) check that there are no cracks in the body around the front pickup rout.
Sadly Gibson era Epiphones are often robbed for parts to put on more valuable guitars, eg tuners, knobs, pickups, bridges etc.
Any issues you find eg changed knobs, should be reflected in the price.
