Does anyone have any good links to web sites that detail the costs involved
in generating electricity from diesel generators?

I do not know of any websites, but it seems to me that this would be a very
hard item to nail down as all of the variables would depend on the brand and
model of generator that you use. You could do an approximation on your own
by taking the following into account;

1-Cost of generator.
2-Run time per fuel fill-up at half load.
3-Run time per fuel fill-up at full load.
4-Estimated run time needed per week/month/year. (only you can determine
these 3 items based on your needs)
5-Cost of fuel. (biggest unknown variable as will change over time)
6-Cost of maintenance needed per X hours of run time. (battery(if electric
start), oil, oil filter, air filter, exhaust system, etc)
7-Cost of rebuilding engine at X hours of run time. (these 2 items are
dependant on mfg's specifications and your ability/inability to perform
them)

I am sure that I have missed items for this list, but I think that these
items would provide you with your major costs of running a generator. And
just like a car there will be items that cannot be figured in ahead of time
as you or the mfg. have no way of knowing what will wear out and when it
will go.

 OK I will be a little more specific, or indeed, a little more unspecific.

Typical diesel generator producing 5Kw of continuous power. How much fuel
will it guzzle per hour?

Do a bit of research. For the 10KW unit I'm presently looking at (liquid
cooled 1800rpm diesel), the answer for 5KW is about 1/2 gallon per hour.

 If you can get by with 3500 watts continous 4000 surge generator. This one
will run 14 hours at 50% load on 3.4 gallons.

I know it's smaller than you asked about, but it would run a 1500 watt space
heater and a few lights and a TV at once. To run a microwave I would unplug
the heater. Our 27" TV says 110 watt on the back and all our lamphs are CF
22 watts each. To run the well pump I would need the 5,000 watt generator.
Since the power is seldom out more than 4 hours where I live. I cannot
justify one right now. It does help to have the kids 3 1/2' pool full of
water for toilet flushing. With 6" insulation in the walls, ceiling and
floor the 1500 watt heater can keep the kitchen and living room plenty warm.
We also have a small 2 burner propane stove to cook on, when the power is
out.
   I should say that the generator I have is 5 HP Petter diesel that I
hooked up to a 3500 watt generator. Not the one in the auction. I just used
the one in the above auction for an example.
  The 5,000 watt on this auction says 9 to 15 hours on 3 gallons.
