Dashcam figment needed for M2 in Surrey

[MikeE]

My M2 has arrived at the dealers today so will pick up in January. They've quoted me £399 to supply and fit a front and rear recording motion sensing dashcam (they haven't told me the model) but think this is a bit steep. Any recommendations for dashcam model and installer in the Woking area?

I had one in my M5 and it was a decent bit of kit, I was happy with mine
