Best pricing for Compaq Power Accessories

Ok, I foutn Laptop for Less and this seems to ahve a good selection of old Compaq accessories:
* Battery for Compaq Evo. $115 for an internal Compaq Evo 400c battery sure isn't bad.
* "Universal DC/DC Stepup Convertor":http://web1.applelaptopbattery.com/ccp5/cgi-bin/cp-app.cgi?usr=50X5437793&rnd=6841936&rrc=N&cip=64.3.228.130&pg=prod&ref=DC%2FDC+ADAPTER&cat=&catstr=&catstr=. This is a mouth full, but basically, this lets you charge the Compaq battery in your car. It is a universal charger so will work with most things (but not the strange Toshiba connector arrggh!).
* "Empower Airplane Power Connector":http://web1.applelaptopbattery.com/ccp5/cgi-bin/cp-app.cgi?usr=50X5437793&rnd=3571400&rrc=N&cip=64.3.228.130&pg=prod&ref=AIR+ADAPTER&cat=&catstr=&catstr=. This $10 piece of magic converts the car plug adapter to an airplane adapter.
