The only thoughts that should be expended on pricing should be done by the sellor prior to implementation.
I remember looking for one years ago and came up with nada. This was circa 2006 and then it was easily 2 grand, maybe a little more. I think there are some others that are highly regarded, but I’d have to re-research it. (Expressive Technologies was one at the time- but only a step up transformer).
Talk to Dave Slagle. He can probably build something cool and not be as pricey. PS: he did a unit with J Jackson but it's no bargain. Still, Slagle is good, I'm not sure what Jackson is up to these days. Those guys collaborated on a bunch of stuff at one point.
