Finally I've found a Gibson LP fitting into my current budget, so the decision came without much hesitation.
The shipment was as expedient as it normally is fgrom Thomann. The guitar reached me in an absolutely perfect condition, and even after a vary careful inspection I couldn't find a slightest blemish. The instrument had been correctly set up; all I had to do was adjust the intonation for some strings, but the neck relief and string action were right on the spot.
I heard lots of good opinions on the BurstBucker Pro pickups, and, indeed, the guitar sounds great in whatever amp configuration I've tried it (I'm an amp/cab modeller guy, so I have plenty of options).
A sweet Les Paul, actually very moderately stripped down Standard, offering a lot for the price. Highly recommended.
