wow, this guy got ripped apart! All he wanted to know is if anyone knew where you can get a 1Dx on a finance plan.... Who cares what logic he is using when he arrived at this decision, nor how he decides to run his finances or weather he pays 15k for a 10k camera, thats a decision he will make and it has absolutely no impact on anyone else.
On behalf of all who paid attention to your initial post mate, i appologise for the pain you have been served with... If i knew where you could get a 1Dx on finance i'd tell you. However, i don't. But what i can suggest is that you could maybe look into a personal loan through your bank... You will have a set payment plan on a set interest rate and you will also get to take home your camera, all bases covered, happy wife happy life
Also, there is a company called CERTERGY these people speciallize in 'No interest Ever' finance on a layby arrangement. So in essence, you get the goods today with a minimum deposit normally 25% and and the remainder of the cost divided over 12, 24 or 36 months. It may pay to give this mob a call and ask if they have agreements with any retaillers that deal in camera gear and go from there...
Good luck on your hunt and your photography work.
