Autozone has a loan a tool program and it is free after you return it. That is what I use.
There is an adapter that has a pivoting end. You pivot it to inline while inserting, then pivot it to perpendicular once it is on the other side of the bearing, it has wider tabs and grabs better.
Sounds like you've made your decision where to buy. If you have a Harbor Freight store close, check them out for future tool needs. Their tools work just fine for the DIY. In fact, if I was a pro, I'd still consider them. Their prices are low enough you can afford to buy two over a big name tool. Which are also likely made in China.
Tried both pullers with my Dad's boat. Ended up using a Dremel tool with a little cutting stone and grinded it out enough to use hammer puller easily. FYI... parts of the bearing are hardened and wont budge but other rings are softer.
