Wow, nearly $100 for a tool to take a bearing out. That's about 1/2 of the cost of an engine nowadays! Personally I've used bearing pullers in the past but I still prefer the oven method. You are not putting a lot of force on the balls or inner race pushing or pulling out the bearing. Also if you do things like I was talking about heating the case, replacing the bearings, installing the crank and then letting everything cool with the crank in you end up with perfectly aligned bearings every time!
