The Transcend DrivePro 220 normal retails at £129 and it's recently dropped to £116 on Amazon.
Today it's on the lightning deals for £86!
A very capable dashcam which includes a 16GB card etc. - the reviews speak for themselves and for anyone who wants a decent dashcam - this may be a good start.
Given that the very, very capable 'entry' Model DrivePro 200 is currently more expensive that this one - I'd say if you're toying with a Transcend dashcam - this may be a good deal for you :)
