well agile probably has some sevens with a hardtail for a good price, also can't go wrong with a used ibanez RG7321/7421/7621 either.
and like it's been mentioned in this thread I would also advise you get one without a trem as well. but if you do want one then there's a few more sevens available to you, like the douglas SR370 you mentioned. agile and ibanez also have their respective offerings which can also be had for really cheap without going into emperion/devries "quality"
