Google LST-C2128
It's the one on hids4u
Haven't fitted it yet and it wasn't the cheapest necessarily but I found a discount code online somewhere that gave 10% off at the checkout
Looking at it now it arrived its not too bad, smaller than I expected so top to bottom of the camera blob bit about an 3/4 an inch.
No idea when I will get it done, some busy weekends coming up but hoping before the end of May.
To be clear it has a Sony chip apparently, still made by small hands in china somewhere judging by the box.
