Is it for work, or for home, as you "its busted requirements would be differant", we had a requirement a few months ago for a ISDN router, we ended up using a D-Link that we had for a test, and then we purchased a Cisco, the Cisco was lots more cash, and took about 20 times longer to configure (saying that, I know have a far better knowledge about routers). So if it was at home I would go with a lesser (cheaper) brand such as D-Link, if it was critacal to you business, and you fancy a challange (and you a flush) get a Cisco.
Thanks
