Much like Deanali I was also ploughing through these threads and asking advice. I had a budget of around 200-250 and also narrowed it down to the models listed: md101, hc47 and the gs80/180.
I got the canon md101 for £150 from amazon, it was a bargain until I used it

.... the motor noise on the recording was pretty bad and I sent it back the next day

. I then opted for the Panasonic GS180 (got it as a last one in Currys for £229

). I have only used it a bit around the house today, but when you watch the 2 recordings the difference between the canon and the GS180 is startling...... so far the Panasonic gets my vote
