Amazon currently has the Apple iPod Nano Dock (for 1st generation Nanos only, not the new color aluminum models) for $11.02. Send in the $15 mail-in rebate valid through 12/31 and you'll actually make $3.98 on the purchase. The dock allows you to sync your iPod with iTunes, re-charge and connect to a stereo in one step. Shipping is free if you spend $25 (otherwise around $5) and there is no sales tax (except KS, ND, WA).
