I'd say MM and KSS about the same and then RB and BBB. There are SO many nice soakers out there though on Ebay that are pretty darn beautiful, that I wonder how long people will continue to stalk the harder to get ones. Personally, now that I knit, I don't care anymore, although I love to look at them and ooh and aah, I wouldn't even consider buying one.
Just FYI, I taught myself to knit about 2 mo. ago from a book - Knitting for Dummies. Took me a few weeks to learn enough to knit a soaker. But I did, and I swear, the last one is something I'd spend a lot for. The hard thing about soakers is I truly think they are worth a LOT of $. More than I wanna pay for one. It takes me probably 20 hours to knit one so they are worth a lot more than the $30-$40 people are charging!
