Dyno Opions Wanted

[Duramax 6.6L]

I am looking at purchasing a new dyno and would like some input from fellow tuners. The three that I am looking at are as follows.

Dynojet 224xLC twin eddie (New dyno just released) 24 inch roller
Mustang MD-1100 twin eddie 30 inch roller
Superflow 800 twin eddie 42 inch roller

If you were to purchase a new dyno what one would you buy and why? Also could someone please explain if a larger roller is better than a smaller diameter roller and why.

Thank you in advance for your input on this.

I have a superflow autodyn 800 series with dual eddies and 42 inch roller, it is great bought it used in jan of 2007 and not one issue with it, have had 900+ HP diesels and even a few pro mods and nothing has ever seem to affect it in a bad way. My dyno was orginally built and deliver in 2004 from the place i bought it and they didn't have any problems either. let me know if you have any questions i feel if you can afford the mustang or superflow they are much better machines but you get what you pay for.
