I haven't made any decision yet, but I think I've narrowed it down. Part of the reason for a lack of urgency is that I do have a guitar, it's just one I haven't felt comfortable with.
I've had it for 20 years and for the longest time I couldn't get any info about it. There's very little model info on it other than the Epiphone name on the headstock. But I googled for late 80s Epiphone guitars and found this article: http://www.premierguitar.com/Magazine/Issue/2008/Apr/Epiphones_800.aspx. To save you the time from reading it, the column answers whether a certain guitar is "trash or treasure," and in this case the verdict was "treasure."
After a bit more research I found out my guitar is Epiphone S-900, with these specs:
25.5" scale.
Solid basswood body.
All-maple neck-through construction.
Rosewood fretboard with 21 medium-size steel frets.
White plastic sharktooth inlays.
Steinberger traditional tremolo bridge.

So now I at least know something about it. I also know that the setup and action is completely F'ed up and has been for years, which is largely why I don't feel comfortable playing it. I keep meaning to take it to a guitar tech, which might just solve a lot of my problems.
I'm definitely keeping it, I just don't think it will be my main guitar. I still crave that Jaguar-style look. The Epiphone is a Super Strat clone, very much a guitar of its time (think 80s rock/metal). And the other big factor is the neck scale. I really want to try out a shorter scale.
It's between the Jagmaster and the Tele thinline. I'm dropping the Duo Sonic from the list. As superficial as it sounds, one reason is I can't get past the color. As for the other two, the Jagmaster remains a big contender. A friend at work recently got the Jagmaster and I played around with it for an evening. Felt really nice.
As for the Tele, I don't ever plan on playing heavy/metal stuff so that's not a concern. Most of the alternative bands I listen to have at least one Tele variant in their guitar rack so I don't have any worries about it being too twangy or "country" ... and I REALLY hate country. The main appeal for this one is that it's semi-hollow, which could mean a fuller tone, and maybe some nice Ric-style jangle.
