It's really hard to beat the Mobius for a super discreet, super reliable, highly configurable, extremely versatile and very affordable camera. There's also nothing quite like it on the market in terms of ongoing developer support (regular firmware updates/improvements/new features), hardware improvements, user community and spare/accessory parts availability.
I use a small LCD monitor to aim the Mobius in my vehicle and after that I let it do its thing for weeks or months at a time and simply pop the card out if I need or want the video. I have a super-capacitor in the ones I use in my vehicle, which I consider a "requirement" in a dash cam at this point.
I also carry a Mobius daily as a pocket camera. I love having something the size of a matchbox that takes great (up to two hours on a charge) 1920 x 1080 video and shoots 2304 x 1536 stills. (and options for time lapse/black & white/warmer/cooler/sharper/rotated/variable data rates/multi-modes on the fly/etc./etc./etc.)
(Edit: BTW, a pocket Mobius also has proven itself to be very handy as an audio-only recorder with the lens cap on, if you suddenly find yourself in need of one.)
I think the mini-0806 has the potential to be a great camera.
@Rayman.Chan has put a great deal of effort into refining this unit. The lack of a super-cap in the 0806 is kind of a deal breaker for me though.
As GJHS says, the A118 with capacitor would likely be the way to go in this price range if you simply must have a screen built in.
