Having spent ages looking for an RCA board in stock somewhere in the UK at a decent price (£140 was the cheapest I found), I ended up ordering a BNC board yesterday. This morning I got an email from B&H in the states telling me they had arrived in stock. Great timing, but thought someone else might be searching too, so here is the link. BHphotovideo Board is £55. They deliver to the UK for about £17 ($32.50 for 10-14 days), you will also need to factor in VAT at just under about £10, if customs bother. Should be no duty as under the limit. Makes the total cost about £83ish.
