I would go for a used HD600 at your price range, funds permitting. If not, the HD598 will do just grand.
That's a pretty good deal for that STX. $110 + $12 shipping isn't bad. Are they a reliable and trustworthy company? I'm pretty iffy on buying from them since there's only a 15 day warranty on open box merchandise. How likely is it that the STX would break and how long do they usually last for? I don't know if it's worth paying the $48 more for a brand new one with 3 years warranty off of newegg.
I think I'm going to end up getting the HD598 since that HD600 is pricey, even the used ones.
