LJ Junior has a "ODT Turtle Shell 2.0" that I occasionally requisition and use with my mobile. It sounds fine to me - plenty of volume while working in the garage. It will probably have won some award somewhere for something as he tends to not buy the cheapest stuff. I have no idea what he paid for it, and as he must have had it for well over a year I suspect they are on to version 6.0 at least by now.
