The DFE-570 was discontinued quite some time ago. It was replaced with
the DFE-580, which is four ste(4)'s instead of four tlp(4)'s; they
were never particularly good, and I think they may have been
discontinued too. At least Dlink changed the model number, unlike some
other cases where they changed chips mid-stream.

I haven't seen the adaptec quad sf(4) for a long time either, though
they were decent cards. A customer who had some was looking for more a
while ago, without much luck iirc.

There are some still being made, though I'm not sure I'd really call
them new - just more of the same of an existing well-proven design.

There's still a market for them in building firewalls where you want
multiple physical interfaces. The original higher-volume usage of such
cards, with port-channelling from servers for greater bandwidth, has
moved on to gig-E. What's left is low volume and niche market, so
sadly they're not cheap.

For the record in case someone's looking for some, these are what we
use, they're quad tlp(4):
