Which Arc Flash Suit?

I'm needing a protective arc flash suit and was wondering if anyone has purchased either of the two I'm considering?

I've narrowed down my search to either the "economy kit" or the "standard kit" rated at 45-Cal/cm2 located here: http://www.envirosafetyproducts.com/category/arc-flash-kits.html

Not sure if the economy version would be as comfortable with the long jacket. Anyone have some suggestions?

Thanks.
