Hi Rich.
The biggest change for you will be the move to WPA2 security. I believe only the B2000v2 did WPA get onboard.
This is an important change that will necessitate changing\updating your adaptors too. Along with that you will be using G wifi vs B.
You certainly do not need to get an expensive zywall unit, nor do I recommend the current crop of N routers. There are some zyxel N products, coming within a year that may prove more useful (actual zynos firmware and vista compliant).
Currently I am recommending the NBG334W and NBG334SH.

zyxel.com/web/product_fa ··· 361862EEBoth have the latest zynos firmware which includes their solutions for P2p, VOIP, gaming etc along with throughputs above 30Mbps. One of the most important features of these two routers is the new guest WIFI, which is a fully dhcp serving VLAN separate wifi(incl separate security settings) that guests and friends can use which solely gives them access to the internet. The difference between the two is the wifi. THe NBG334W comes with the standard feeble 2dbi antenna whereas the SH comes with a 4 or 5db antenna and higher output 400mw?? not quite sure on the figure. The SH also touts the Super G wifi speeds.
If you must have the higher output and antenna expect to pay an additional 10-15$
Street prices are in the vicinity of $50-55 for the W and $65-70 for the SH.
To answer your question, If I was buying for family I would get the above two if wifi needed, or the zywall 2 plus for strictly wired (limited thruput of approx 24Mbps though). I hope this helps.
Oh yeah, you will need adaptors. The NBG series is atheros based so G, atheros adaptors will work with the above nbg SERIES. I note in the spec sheet picture it shows the G202 usb adaptor, G302v2 pci adaptor, and the G120 cardbus laptop adaptor. Not sure if those are super G capable though.
