The Tekram controllers are good, but they will only work in a 5V PCI slot. I am surprised that Tekram still has not redesigned this part for the newer 3.3V slots. See
here for specs that state it is still 5V.
If you are sure you will only use the card in a 5V/32bit/33MHz slot, or a 5V/64bit/33MHz slot, then it is not a problem. If you wish to keep the card longer, then you will likely need to be able to plug it into either a 3.3V/32bit/33MHz slot, or a 3.3V/64bit/66MHz slot.
Instead of the Tekram, I would suggest
this card. It is the same board layout as the Tekram, except it supports both 3.3V and 5V slots, and will run on a 66MHz bus. I've used these cards before with no problems.
Just my 2 yen's worth...
