I've got a "ST62-TX" in Fiesta Red. Most gorgeous guitar I've ever owned.
As I understand it, the main differences between this and the advertised "ST62-US" are the body (alder in the TX, basswood in the US) and the pickups (the TX comes with Texas Specials, mine have mysteriously been replaced with Irish Tours :D).
When I (or my wife, actually) bought mine in Denmark St 18 months ago, it was £550 new. I tried a couple of the ST62-US models that were there, which were £450 new, but I'd already fallen in love with mine and I really wanted an alder body that day. (Btw, don't be put off by the basswood, I was just being snobby that day - I've got a basswood JV Squier that sounds really good).
I've never bought a guitar off the internet, but if I had to I would buy another ST62-TX without trying it - all the ones I played were really nice and very consistent. I'd buy another of these before any US/Mex alternatives up to twice the price, I think they're that good in that price range.
Personally, I'd want to try the ST62-USs again before buying one of those - they didn't feel quite as nice in my hands. But they still beat the 20-odd USA and Mexican strats I played that day. Bear in mind I like vintage necks (21 fret, curved board), so that's why it beat things like the Highway 1 for me...
