Very good results have come from the new Vipec Plug in
ECU from over east.
A few cars on Rexnet have them fitted.

Apparently a piece of piss to fit and tune. Sean from ASG or Leigh from RMS would not have a problem and get good results from it. If they can tune a Link G3 then this is even easier. Particularily if you get the optional closed loop wideband control for quick tuning.
Has a lot of Motec M800 features at a very competative price.

One very important consideration is local and active support via forums / firmware updates from Ray Hall on the Vipec website.
This would be what would sway my decision.
Local Support.
They should be $1600ish + tuning
2nd hand Power FC if your on a budget.
