Thanks for the quick reply.

My father-in-law has a huge tiller on his tractor. He does the
initial tilling for us every Spring. So I need something to go
between rows, or to use in the flower beds, etc.

Does the Troy-Bilt seem about the same as the Mantis?
The Troy-Bilt is he

It's a 4-stroke, which means no gas-oil mixing.
I have a $100 gift certificate for Amazon.com, and they sell the
Troy-Bilt (not the Mantis), and free shipping.
