Depends on the other hardware and the application.  Using two of the
same cheap card in that situation is a pretty good bet, since that
will be the most likely configuration for development testing.  The
PCI NE2000 is just plain a bad design, so I've heard, it's sort of the
Ethernet equivalent of a Winmodem.

My advice would be to buy a couple of cheap cards (a matched set, same
model and brand), but be prepared to throw them away when you are
thinking of adding more systems or trying really demanding
applications (streaming video, Beowulf).

Didn't say it wouldn't; just that in some situations it may not.  Some
people have more demanding definitions of "work fine" than others do.
Probably the original poster is gonna be pretty relaxed---but he may
not be so relaxed in September after he's gotten a taste of high-speed
networking ;-) At that point, if he's using cheap cards, he should be
prepared to throw them away.  (But I'm still using a _real_ ISA NE2000
-- probably 9-10 years old -- in one of my boxes; I have others where
I won't accept less than a 35 Mbit connection.  He may never need to
throw those cards away.  He may chuck them in disgust next week.  Who
knows?)
