Night-vision goggle recommendations?

I'm considering getting a night-vision rig for the darkroom, both for loading film and for tray development.

I think the IR type with built-in illuminator would be preferable to the (1st/2nd-gen) amplifiers, since my d/r is really dark.

Anybody using one of these care to comment?

I would prefer info on relatively recent products, as this technology is evolving rapidly.
