Three years MTBF? Yikes! My oldest wireless router is a DLink DI-624; it's 11 years old and still works (the AC adaptor failed, but I replaced it with generic adaptor for $15). It's my loaner unit now.
My latest wireless router is a Buffalo WZR-300HP. Very nice router, only $50. Good signal, good speed, came with DD-WRT built-in.
For the sum total of all of my wireless routers (two pocket/travel USB-powered TP-Links (one modified with extra RAM to install Grugq's Portal), one Cisco industrial/small-business router/firewall, the two DLinks, plus the Buffalo, total cost for these six, about $600 (purchased over a fifteen year period. All of them still work. I guess I'm pretty good at reading specs and test reports...
I see you've stopped buying Apple products, Jason, at least as far as wireless routers/switches go... Good move, since, from what you report, Apple products don't last. ;-p
