I have to say that I enjoy watching GB do it's thing. I have it set on Tony's long SP herb run and it's doing an amazing job. I've used it for about 5 hours total so far, and am very impressed. I use this while I work (from home) and enjoy coming back to a few hundred gold worth of herbs in my bags in an hour's farm. Well worth the investment.
i second that ... i have been running tony's awesome profile now for three 21 hour sessions mining and herbing without any probs at all ... and it's still running, right now = )
