I'd consider a Special, you know, the TV Yellow ones with p-90s, rather than a Studio. To me these are more like 'real' Gibsons in that they resemble historic models. Mind you, that says more about me than the guitars we're talking about. I dig the Goldtop Tribute with p-90s as well as it's actually very close to the first ones Lester used in the '50s. I don't know if they are still available.
If I was going for the humbucker LP experience on a budget, I'd get an Epi and maybe upgrade the PUs. That said, for recording purposes I find it increasingly more difficult to fit a humbucker in a mix, and like Peen said, if I were after Led Zeppish tones, I'd seriously consider getting a very basic Tele, like a Vintera, a Player, or something like that.
