Maybe too late for this info request, but for others who may be looking... I've been pretty happy with my Cisco Linksys E4200. After having bad luck with reliability on my previous Linksys routers, I think they've finally figured-out some of the power/heat issues that caused my WRT310N to fail. I was also very pleasantly surprised when I first tried a loopback to test my DiskStation NAS, and it worked first time! I'm not sure if my settings to get Replay Show sharing to work also "turned on" loopback, so I can't say for sure it would work "out of the box". But, I suspect it would.
