Smart TRE - how reliable ?

[Ozboc]

Im very happy with my Gear Indicator with smart TRE, never failed me to date. (made by Speedohealer)

Ok so i would be better off replacing my 16 bit ( if it is ) with a 32 bit ? from what the forums say its easier to flash the 32 bit and far cheaper than the 16 bit ?
would one from a 2003 model busa go onto the 2000 without to much mods ??

found one on ebay (USA) here is this mod well worth it -- or should a power comander be the way to go ?
