Should I? I haven't heard much about JTK2 except that they're really versatile.

Tough decision. I own a MIM Strat and a Jet King 4 and I love them both equally, they're both amazing guitars.

I'd probably get the Jet King though, if I were you.

I have a MIM Strat that I'm VERY pleased with. I have also owned an Ibanez JetKing ( an early one) that I thought was cool but really sounded crappy and felt even worse to play. I was going to upgrade the electronics but even the pickup selectors were positioned so I'd turn them on and off accidentally. I got rid of it quickly.
