Alternative ways to get more character slots

Yeah, I can see that.

I was going through this thread (HOW TO: Multiple D2R Instances (requires two accounts)) to see what would be involved and it does seem like a major pain. I honestly don’t know what else to do. I don’t want to delete old characters and I feel I need at least 10 character slots for each ladder ( I like to play at least 5 different characters and a mule for each).
