In your opinion, what's the best replacement? I've never used the type of mesh wheel that Devin Castellucci linked to, but I've always met good results with flap wheels. Anyone have any good recommendations?

Depends what your desired outcome is. If it's removing metal in a hurry, I would get a disc sander and call it a day. If it's light metal removal a flap wheel is good. If it's deburring,
this is a good choice, or
this or
this (we use these last two the most as they are dirt cheap, work well, and conform to irregular surfaces a bit better than the EXL wheel. The EXL wheel is really long lasting and super nice for deburring edges on parts that don't have areas that need conformity.
