Another +1 for Ubiquiti. Had a bunch of high end prosumer stuff, ddwrt/tomato, etc. It really is fantastic stuff at least on part with ddwrt and well matched hardware to boot.

Their cloud management stuff is solid(and free with spare PC!) which is great if you help your family set anything up.

Ars did a great deep-dive a whole back[1], it's a pretty good read.
