Try living in a country where the average income is $7000/year! (and photography budgets are equally low)
But what's your point ? Do you really expect DB manufacturers to adjust their prices according to your country's GNP ?
I do not know how many people Leaf or Phase have working on their backs, what their pay is and how many items they sell each year, so I won't even start commenting on prices.
However, the other day I went through my job files for this year, to calculate what I charged my clients for ( analog ) film & processing and polaroid.
It's been a slow year, and I shoot low volume ( still life, 2-3 shots per shooting day ).
It adds up to roughly 25k €, and the year isn't over yet, and personal work is not included.
In my case, I do not need to spend much on file processing, data storage and such, and can still charge the same or even slightly more when shooting digital compared to using film.
A few other aspects factored in, an Aptus 75 will be paid for within 2 years or less.
I'm working in both Germany and the US, which means I get low to decent budgets ( that's Western standards ), nothing too exciting.
That said, I agree with the above postings, if you can't finance a DB, you are probably not in a position to actually need one, being a professional photographer for advertising .
At this point, it might make more sense to stick to film for LF or MF, or just use a DSLR if you don't need camera movements and can accept the characteristics of 35mm bodies.
Just my 2 cents...
