I got one of these off eBay for £23 recently:

It’s very useful overall, but I find there’s too big a jump in size between each expander, but I’m not complaining for that price.
To give an example of sizes, the largest of those expanders just squeezes behind the bearing of a Shimano press-fit BB92, and gets it out nicely. An example of gaps between expander sizes: The smallest expander (1) was too small for a 6802 bearing, and the next size up (2) was too big, but after grinding the edge of (2) down, it fitted a 6802 just right.
I can double check the fitting with a 6803 if you want ?
Overall, OK product, but I would only recommend it for blind bearings where you have no choice – for parts like suspension linkage where you can get a bearing driver behind the bearing, I much prefer pressing the bearings out.
