"iGo EverywherePower 130 Series Kit for Treo 600" is on sale for $79.97, regularly $159.99. I believe that is the standard everywhere130 bundled with the Treo 600 tip (which I don't need), but this is not a bad deal for the adapter itself. Adapter supplies 100 watts max.

After 20% off, and with free shipping, this is about $64. Not as good as the $30 RadioShack deal from January, but that was in January, this is now. This unit is great for travelers with lots of electronic devices--carry one adapter, and just buy appropriate tips for your devices and laptops.

While I was there, I also sprung for the 4GB microSDHC for 19.99 after $20 instant (?expires) and $20 mail-in (expires 8/31/08) rebate.

You might consider instead the 2GB microSDHC for $9.99 after $10 instant (expires 8/13/08, 11:59pm EST) and $15 mail-in (expires 8/31/08) rebate. Not as good as $3.97 deal but, again, that's not available now either.

It's a good price for this unit, but...

1) I had one which broke in 2 years
2) It's a heavy one, heavier than my laptop + cell phone + camera chargers combined.

FWIW, I've had very good luck with the iGo system. Used on several laptops and multiple different pdas, cellphones, etc. As I recall there are a few Dell laptops with proprietary charging systems that don't work; but they have (or had - didn't check before posting) a very easy to use system to check out compatability on the website.
