Oh! Thanks for the update. I'll check it out though will probably just toss by biz to @fdeckHe has the v3 up there now. There's also the German kit that's been linked in this thread and a few other places. Haven't seen the price tag on that one yet. I've considered doing an open source one similar to my variable LPF onboard preamp, but right now I have a very full plate with commercial design work and it wouldn't be all that different from @fdeck's anyway.
