(Thanks for the input krazy!!)
there are only a handful of modified ones out there. Rob was working a set to run some numbers against his manis. I have never heard how that project panned out. 240 did his last set for me, before he moved on. So, unless Rob is going to manufacture some, there aren't anymore.
