PCMCIA ...USE BOTH SLOT ( EXTENDER )

[IBM A31 & 600E]

ok, i was looking around the forum, and another member mention using a pcmcia card extender to allow you to use both slots. i currently have a port firewire ( type III ) taking up all the space. has anyone used these extenders to allow you to use both slots. SYCARD.com was the link for this type of extender, any other web/store that has a device. asking 89USD for this and $26USD for shipping....its like $ 1 million CDN

thanks for any help
