Okay, I searched around and I understand that the QPD Belt Drive from Brent is a 2.458:1 ratio (59/24) and it's a little smaller than the stock Speedmaster.
My pulleys are trashed. The teeth have been chewed to crap by, I guess, road debris, gravel and such. I'm 99% sure this is where my squeak comes from. They look a lot like this (picture from the website below, not my actual pulley):
I'm talking to the owner of Supermax Belt Drives (http://www.supermax.net/) about fixing the pulleys with their poly overlays but they don't have a 59 tooth overlay. the closest they have is 58 tooth. Since they machine off the teeth and press on the overlay, it can probably still be done, but will this have any kind of significant effect on the final drive ratio? I guess that changes it from 2.458:1 to 2.416:1. I'd actually prefer to go higher rather than lower as I do more long distance travel these days. Might ask him if he can go up to 61 tooth.
What do y'all think? I'm afraid this might be pretty darned expensive to do but by all accounts, and not just from the Supermax website, it will fix it for life. I'm trying to decide if I'm "pot committed" or if I should go back to chain.
