Has anyone had any experience of these cards?

Is the ET card worth the extra money and does the bandwith manager really work?

Is throughput comparable to an external router such as the CISCO 2501?

I'd stick with the Riscom cards.  They're rock solid and good enough to use in Telecom applications (where I found out about SDL).  

Compared to a Cisco, yes and no.  Depends on the Riscom you want.  Consider that a 2501 costs about $1300 in the SF Bay Area these days.  It has two wan ports and two ethers on ours.  That's it.  Also, if you filter a lot, it tends to be slow.  I also wouldn't suggest two T-1s on it.  However, you just can't beat Cisco's protocol handling in it.

A Riscom/N2 has two E-1 WAN ports (2Mb, not 1.5Mb max) and can even include the built in CSU for the same price.  On a P-90, the card can service both ports at full rate.  This is a fast card.
Now add about $800 for the P-90 no monitor and a pair of 10Mb ethernet cards and you've got a Cisco if you only need IP filtering.  In addition, you can have up to four cards in the system for up to 8 wan ports.

If you want more speed, you can get the T-3 version or the new DSL version (!!! T-1 to home here I come) version of the card.

Finally, having worked with SDL on some million dollar projects, I was able to work with the owner.  The company is small, but more than willing to do custom software on the card for special situations.  We were trying to do "almost HDLC-LAP/B" for telecom work.

Thanks for the information.

I have already ordered the ET card though as I like the sound of the bandwidth management features and it claims to handle up to 7Mb/s.

I'll have to see.
