dont part with your cash until you know for sure it is what you want...The Esp/ltd Truckster is an awesome guitar...not sure I like the finish (sort of metallic silver/grey with big blotches, sort of burnt looking) but it plays really really well.
The Prs you saw that buzzed was one of the SE ranges...they are almost like the Epiphone of PRS...what do Prs Standard Mahogany guitars, or Ce's go for there? I love my Prs and will recommend a Prs to anyone who can afford it...or cant (I know I couldnt afford mine at any other time than the time when I got it...never again will I be able to spend to much).
I like the idea of Heritage...I'm sure you know, but they are guitars made in the old Gibson factory, by (mostly) old Gibson worksmen etc...and said to be much nicer than current Gibsons.
Also a Deluxe American strat is an awesome guitar...for your needs, look at one with a humbucker in the bridge...I have a mate who owns one, and it si simply amazing.
Also, quite a bit cheaper, but still very nice is the Yamaha Aes range...I like the Aes 620 most, but the Aes 920 (is that right? with the quilt top?) is also really nice.
Otherwise, check out some Framus guitars...I tried a Framus Diablo a few days ago, had an ovangkol NECK and just sounded so sweet.
