you seem to have a thing against Les Pauls (which is stupid in my opinion, but each to his own) but as such I think you should definately not buy one...yet.

whilst tone/sound and feel are all very important...the feeling you get about a guitar is also important...a Lp that sounds great, but doesnt inspire you in no good at all...so I would go with the Jackson option...you made your mind up a long time ago...and you know it!
