Unless you really need cardbus and/or you don't have any ISA slots, I've had good luck with the ISA Vadem VG-469 based bridges. Most of them have two pcmcia slots, and most of them have those slots in a 3.5" drive bay. I've had them work great under linux, windows, and openbsd. You need to make sure you have IRQs mapped to the ISA slot in your system, else they'll just hard lock the system when you insert a card. Otherwise, they work great. I've used lucent silver wlan cards on them a number of times.

The plus part is the price; I've purchased a few of these on ebay for under $10.

This is the vendor (and card) I've purchased:

The 'swapbox'. It even has a cool name, if it was only 1980 again.

As for PCI based versions, I would stay away from PLX based bridges; they are not very well supported. The Ricoh *476 chipsets work great under linux; not sure about the voltage issues. They will do cardbus under linux with no problems; freebsd & openbsd didn't like using cardbus cards, but standard 16bit cards worked groovy. I could be wrong on this, but I think the dlink bridges are using the ricoh chipset; I've seen them sell for around $30 new. You should check the chipset on the dlink card, befor you purchase them.

Hope this helps,
Eric
