I do have a nice used shaft if I choose to do the install w/o the tool.

For anyone that has the Proform tool mentioned above, is it machined properly to not ream out the bushing excessively? Some of the Proform stuff I've had in the past has been pretty sloppy on fit & finish, so I don't trust anything from that company. The other option is to hunt down a "genuine" MIller C-3053, but it may be more expensive.

Good news: I have a Harbor Freight 20% Off coupon for one item good through the end of the month. I can get their bushing puller kit for about $60, and like that idea better than using the "official" tool that screws into the old bushing, since the puller won't be cutting threads that could leave brass debris in the engine.
