I run a Toro 32" WB with T-bar controls. It's a great unit, and I don't have any complaints. Just about any of the major companies (Toro, Exmark, Scag, Bobcat, Gravely, Ferris, Etc.) are going to have top quality machines. Best advice is to go with the dealer that provides the best service. The 32 WB is a beast, and much more productive than a 21" mower. Unless your properties require extensive use of the 21, I probably wouldn't spend too much money on one, because you'll be using the WB wherever you can. I do 1/4 to 1/3 acre lots, and my 21" only gets used on one back yard that is so hard to access, I can be done with the 21" by the time I get the 32 into the yard.
