Summary I have bought the Cisco SRP527W-K9 as a replacement of Draytek 2820vn.
This is an excellent low cost and well-built security router.
The device configuration is browser-based and easy to understand.
The SRP527W includes simple content filter that supports blocking by keywords, URL and IP range.
Wireless performance is good enough, outstanding wireless throughput speeds between one Boxee device, four laptops, two iPads, one squeezebox, and two iPhone. I didn't have any connectivity wireless problem at all. However wireless range wasn't that good.
Good VOIP sound quality however VOIP configuration is confusing.
Price is around 200 to 250 AU$ which is acceptable, good value of money.
