I’ve actually been looking into these XLR camcorder adapters. Here’s a summary of what I’ve found:

http://www.beachtek.com – Mounts to camera. Various passive adapters. Some with phantom and audio meter. New unit with preamp (DXA6HD).

http://www.juicedlink.com – Mounts to camera. All include preamplifier. Options include phantom, 2-4 XLR inputs, audio meter.

http://www.studio1productions.com – Doesn’t mount to camera, and no phantom or preamp option. Option for 3 XLR input. Plastic case.

http://www.signvideo.com – Mounts to camera. No phantom or preamp option. 1 and 2 XLR input options.

The juicedLink website has an interesting demo video, showing how a preamp can reduce camcorder hiss while recording fine audio detail:
