You shouldn't really need to do all that much configuration... pretty much any simple 802.11g router will do. Don't bother getting one of those draft-Ns; too many problems with those (with stories such as killing neighbor's wireless connections...yeesh).
Since you had a Netgear router, it probably wouldn't hurt to just get another Netgear router since you'll be more familiar with the interface and how to do stuff, since they haven't changed it all that much for these few years.
If all you want is basic wireless routing (no print serving, sharing a hard drive, hooking up a regular phone for VoIP, etc), then I suggest the WGR614, which is what I'm using right now. Haven't had any troubles with it.
