Keg Handtruck

Anyone know of a place in USA selling a KegMobil www.kegmobil.com.au or
something similiar?
I don't want a full size Hand truck, even one with a keg hook &/or
rounded back. They are just to big and hard to find storage for in NYC
living.
The KegMobil is small and perfect size and will help when I go on a keg
run to fill my Sanyo draftmaster.

Thank you.
