hi how much does it cost to get a MF camera and a standard lens?
Depends on which system.
A TLR w/ a fixed standard 80mm lens is about $80-$250 depending on brand, model reputation and geneology
A Mamiya RB67 system is cheap. Within $1K you probably get body +3 lenses
Pentax 67 and 645, no longer as cheap as the lens has become more expensive due to the 645D (probably $600-$800 for a Pentax 67 body plus 1 lens)
Hassleblad is not cheap at all (but of course cheaper than before digital)
Be prepared for the running cost.
Film is about $8 per roll (10 shots only on a 67 camera). ($5 for some B/W film)
Dev is about $5.50 to $6.50
Scan to CD is about $15
So 10 shots, you pay ~$28.50 (assuming color film)
6x6 you get 12 exposures for the same film roll.
645 you get 14 exposures.
If you can scan, of course cost goes way down after the initial investment of the scanner.
Then again a better quality V700 costs $900;
Even cheaper if you can dev on your own which is dirt cheap AFAIK from various threads around here.
If you want to do this for fun, enjoying the process, tonality, look of film, its ok.
If you are looking for current (esp. K5) like ease and quality, don't even try.

So far, from my own trials, at best, you get quality like a K5 with a so-so scanner (unless you pay out more for a better scanner, software and work hard to find the optimal scanning method).
If you print from negative and print big, I certainly believe they can be different.
Eg. I see much more detail on the neg just using a loupe than from my scans, so I'm certainly not bringing up the full potential of the neg.
Frankly, for 1024x768 size screen presentations, any option can do it (ie. even 35mm film, 6mp camera, etc) .
My few cents
