In case anyone wanted to try out thumbie shifters, I have run these Sunrace thumbies with great success and have no complaints. They are 9 speed compatible, friction of course.

$9.80

These are the same one that Rivendell sells for $12 member and $17 non-member.

I know old XT ones fetch a premium on eBay and the Pauls Comp Thumbie/Dura Ace combo can be around $100. And these have a claimed weight of 109 grams, which is lighter than the Pauls/Dura Ace combo (133 grams). Not as slick and well built, but good enough for daily riding in my book.
