I would like to eventually get one and so I wanted to know.... Should I stick with the $100 device that is suggested by Big Al? If so I don't believe I can ever afford one. The reason I asked is I did an e-bay search and found some very similar device selling for like $15. If these would be safe I might actually be able to get one, one day. I would rather get the name brand one but with my current employment static (partially employed) I wont be able to get one. The jobs in my area are pretty scarce. Unless you have 5+ yrs experience with a degree. Any advice?
