I bought this model's big brother, the WRT3200ACM, refurbished direct from Belkin/Linksys a couple of months ago -- at only $99US I couldn't pass up the deal. So far it's been rock-solid, giving faster and more reliable connections than the Linksys EA4500 it replaced.
Yes, it's larger than most comparable routers, but I knew that before I bought it and I actually like the size. As for the design, I consider it "tech-industrial" rather than "uninspired". (In truth, the design is inspired by the classic original WRT Wi-Fi routers, which are still highly regarded after all these years.) It doesn't blend well with the decor in the average living room, but it's fine for a dedicated office/computer room.
I gave the old EA4500 to my style-conscious girlfriend, who was switching ISPs (from verrry slow DSL to cable) and needed to provide her own modem and router.It still works fine, and fits in well with the decor in her study She's on a slower broadband tier than I am, so an N-class router is more than adequate for her needs;
I'm actually looking to upgrade to a faster service (possibly Gigabit fiber) in the future, and I have a much more extensive home network than she does; I don't actually need the WRT3200ACM's full capability, but it should help keep me future-proof for awhile. And it adds a welcome dash of color to an office dominated by dark wood and black boxes.
