I think you will find they are sold by heaps of different companies,
I bought mine from super cheap and its a "rydge rider" but i see Tigerz11, proflo which you can buy from "Bursons, and also Terrain Tamer sell a copy, also Ironman do a flopro (ironman will be on here in a minute saying its totally different but you judge for your self).
The only change i can see is the colours they get painted, like i said others will say they are not but you look at them and judge for your self, i personally dont see any difference bar the colours .
i have one of those compressors
bought one after seeing nathans at sot
$169 from supacheap
brilliant compressors for the$$
looking at mounting a tigerz11 tank kit in tray
might even put it behind rear seat
