Thanks for explaining that Keith. I was really impressed with the YardMan in that video - it looked like a ride-on I could relate to (I don't recall a small one I liked previously). It has a chassis, and in particular a front axle, that look like they'll stick around for a while. On the other hand, it didn't look light-weight.
If you find good information on the 8/30 please post it so others can use it.
