Uhh. Well, I mean, it's not like there's a huge variety of Strats at that price. You can get a standard Mexican-made Strat for something like $500, or an HSS Strat for about the same. I would say an HSS Strat is good for punk and alternative so I'd recommend that.
The HSS strat would be great for that you can get alot of different sounds out of it
For punk i'd just get the standard, you dont want a humbucker on the bridge , you want MOAR TREBLE!
