I have been using Gunbot for a while now and it has been working great for me.

 I have purchased from CaptainCorporate and he helps with everything from buying to insane of silly questions I asked

 There seems to be a great new version coming out that promises less waiting time on bags, hopefully if that works than I would be a happy camper, should check that one out.
