This is the little Aiptek AHD200 High Definition Camcorder currently for sale from QVC at £120.84 + £5.45 p&p.
Seems to have good reviews from pretty much everyone that has used it. Stored 60mins of HD footage on a 2GB SD card. Okay, you're probably not going to challenge the likes of Spielberg et al, but this is still cheaper than the most basic tape based standard def systems available at the moment.
Hoildays coming up - I'm going to get one!
This is also selling on the Amazon site, listed as one of the Deals of the Week, at £145.
