In terms of brand names, I definitely support the use of LaCie products, Siig, Belkin and Syba make good products as well.
TI is the preferred chipset. Something to keep in mind though, is that there are different revision chipsets. Unfortunately, there's no running list of which specific ones work best, or better than others.
Agere is also a "working" brand, I've used a Belkin 3 port FW card with an Agere FW chipset, and it worked very well, however I'm sure there are cases it wont, because computers just aren't that simple.
Some VIA chipsets work, some do not, so it's hard to say one is good, one is bad. Individual use has so many different experiences, so it's impossible to say yes to one, and no to others.
I would suggest that LaCie card, but if you find other cards in different price ranges (FW cards aren't cheap), I would say it's well worth checking other brands, to see if it's TI or not.
