Those are awesome, and, with a baby due any day now, I'd love to get some!! They're available through the Lowe's website - here's a direct link:

betsyfieldsdesign® 48mm Race Car Knob
Item #132237
Model #PBF952Y-RED-CP
Here's the kicker - Lowe's won't ship to Canada!!
Anyway, if anyone orders some, I'd appreciate it greatly if you'd throw in 2 extra for me and send 'em my way! If anyone can, pm me for details!
Thanks,
Chris
