I ended up buying the MiVue, it arrived in the post today...
Before I purchased it I queried whether there was a longer cable (possibly a 2m) for the front camera as, in my opinion, the supplied 1.5m cable was likely to pull up a bit short on the ST1300.
I was pleasantly surprised when they told me they would source a 2m cable and send it at no cost to me once I supplied evidence (serial number) of my purchase.
So, hopefully the new cable will turn up in the next week or two!
Good to see good customer service is not dead!!!
