I used to own a SX tele thinline. Have played some of their strats too, buddy owns a SRV strat. Some hype was going on a few years ago, like " as good as originals" or "7ender forced them to change the headstock-design because of their quality"!
The truth: pretty good guitars for THAT price (I've paid 150.- for a new SX)! Nothin' more!!
If you want the "real thing" for little money, try to find a japanese Squier!
The best chinese guitars can not compete with the quality of early/mid eighties japanese guitars, and I guess that's why we all are here at this forum...
