I've a DR32,which is great all rounder with fantastic day and nighttime footage.Doesnt come with GPS though.Not that I'm bothered as I tend to know where I am!
However...the new kid on the block seems to be the mini 0801.Great all round footage,tiny footprint,very easy to remove and has an internal power source,so you can take stills and view footage at the roadside(if need be).Also has optional GPS,1080p and is getting great results.The price is good too.

Thinking that this will be my next purchase!
