Speaking of which, I have yet to see a consumer battery charger that isn't incredibly cheap feeling. Even ones for charging different chemistries or that let you set current rates are a mess of low-quality molding and cryptic button presses.
Panasonic does have one that charges over USB (micro-USB input though) so you can use an old 5V Apple brick and only take up one spot. It also supports USB out via a full-size USB-A port. Picked one up since I liked the idea of being able to use AAs in a pinch for recharging.
This is expensive but so far pretty nice. It's about the size of a console, though.

I've never had a problem with the basic 4-cell chargers that Panasonic includes with their Eneloop starter kits, other than the mildly annoying fact that they cover more than a single plug on a power strip.
Build quality seems fine, and I've been using them for decades without a single failure, so I've never seen any reason to even investigate alternatives.
