http://www.machv.com/blitzdcgauges.html has them for $216 plus box. THey also record readings via the live wire box. Black or indiglo faces for them as well. THat is what I am going to run come spring when I do my 2jz-gte swap. Most places that carry blitz can get them. Definately my favorite gauges.
