I had one of the Korean-made Tribute Legacy models for a short time. It was very similar in feel and build quality to a MIM Strat - not bad, but not outstanding, either. They really don't compare to the US-made G&L's, I might even suggest that you'll have more options to choose from, if you look at the various Fender models.
Going in a slightly different direction, if you want a really
good Strat-style guitar, look at the Godin Session models - Godin Session.
Beautiful guitars, incredible build quality for the price.
