I have been using a Maha MH-C9000 Wizard One for several years. Much more compact than the linked unit, which seems optimized for C and D size batteries.

I have been quite happy with my unit. Once you get your head around the UI it is straightforward to snap the batteries in (AA or AAA), then click Enter twice per battery to start the charging process with default parameters.

If you want to tweak the charge rate then it is a few more clicks.

I have found the ability to cycle/calibrate a battery (or several at once) and tell me the actual mAh capacity per battery to be useful for weeding out weak cells and capacity matching of batteries when I want to maximize the run time of a device, such as my high output LED flashlights.
