Help With Purchasing New Shen Hao 5x4

Hi - so I'm about to purchase a new 5x4 , and want one of the Shen Hao TZ models. I currently have an Intrepid with a Fuji 125mm. I can get the A model in the UK for £800, or the C model direct from Hong Kong for just over £1000. I'd prefer to stick with sourcing within UK for support etc, but what do you guys reckon, should I go for the C instead ? I'll probably go with a wider lens shortly, what is the shortest the A can handle ?

BTW - The C model is not listed on their web site but is being sold online by them on The Bay.

Thanks for help !

As it turns out the UK supplier started listing the C on their website today so have ordered that - happy days
