buy.com has the Belkin F8U1500 infrared keyboard for $34.99 and shipping is free. They have had it for as little as $22.00 with free shipping too. This keyboard sells for over $60.00 at retail stores I have been to. It has a dedicated number row, (unlike the Pockettop I was using which I broke). It works with my SL-6000L using Craig's irk driver (irk-zaurus_0.11.1_arm.ipk) which can be downloaded from
irk-zaurus_0.11.1Use the "F8U1500T" layout and "SL-5600/SLC7xx" as the Zaurus model (for the SL-6000L).
