Personally, I just love them (well, once I've swapped out the stock bridge), they play well, sound (and look) amazingly good.
I'm up to six now in different guises (five Gibson, one Hamer) and my only regrets are, i) that I played so many other brands before finally settling on them and, ii) that I didn't pull the trigger on a cardinal red Twiggy Ramirez prototype that was on sale in the US a couple of years ago. I've never had itchy feet with them either; never this clawing in my mind that I need to sell on for a change.
I posted elsewhere that I'm a slightly overweight guy in my 40s, I pull on a Thunderbird and I feel like a skinny guy in my 20s. They're like magic.
