There's a car commercial where the actor asks the simple question - "when you turn your car on does it return the favor?"
I tend to see the same in my camera gear. I normally have the WRS sitting on the tripod in my living room as I generally see it as a piece of art as well as being on the ready for then the mountains out my rack yard light up. And I never tire of seeing the setup so the answer to the commercial's question is yes.
I think I've finally found the perfect mix of lens, body and back. The lenses I have are all more than capable of outstanding results - so long as I keep my end of the deal; the body is - well I believe it's "perfect for me" [what may be perfect for me mightn't work for everyone]. The third part is the back and like the lenses is more than capable of outstanding results so long as I keep my end of the deal. [This is not to say that I'm not interested in the newer backs from Phase, primarily the P65.]
Software, dealer [which in my opinion includes service and support] and manufacture all bring a lot to the table as without these there simply wouldn't be the main three items above.
Price [at least for me] is the least important and I'm not made of money either. Yes it's important however buy right the first time and save money in the long run; this is where the art of negotiation enters into the mix. Landscape photography is not my hobby it's my career and one I take seriously so when I decide on a set of tools I want the very best I can afford so I do my due diligence researching, testing the tools as well as understanding the market values. This is where finding the right dealer is so important.
I decided early on that I wanted a dealer that specializes in one medium format back so if/when there was a problem and I called I wouldn't find that the guy that specializes in that back didn't show up for work however the other guy would attempt to help me out. I also wanted a dealer that had a good reputation, not only with the manufacture but more importantly their customers. It's one thing to be named "dealer of the year" it's another having the loyalty of their customers. All this come at a price. A price that is well worth it.
There you have it, my little dissertation on what makes my MF system tick for me. When I turn it on it returns the favor.

It's also interesting to me that currently "Price" is 32.69% to "Service and Support" is 23.08% I figured it would be the other way around.
