There is always this one,http://www.race-technology.com/dash2_2_31.html which i believe will work with aftermarket ECUs, several of the Supra club use them with the Solaris ECU, but there a bit expensive.
The Greddy infometer looks quite good actually, there is always the HKS camp2 which i think does the same as the Infometer.
yeah they promo that dash on their site (haltech) but it's to much money for me perfect for racing but not daily drive think Steve (MrLizard) has one of them fitted actually... might be wrong though. Wonder if thats why they got rid of the haltechwin that they used to have so they can sell them yokes.
