Bob Gecco said "2 Hours of fun loving labor..." to change the oil filter, and presumably the oil. 2 hours? This seemed (to me) to be quite excessive unless you were just goofing off while changing the oil and filter. So, I made an estimate, with liberal times, starting from scratch and included cleaning up aftwards. It turns out that the time it takes is 1.5 hrs (rounded up), and that's with liberal time estimates for each step.... I'd subract 20% for a more realistic estimate of 1 hr & 10 minutes.
The point is only that its not really a 2 hr job... and if you're really motivated it can probably be done in as little as 30 minutes or less, including cleanup.
4/14/09 Modification:I made a correction to an addition error I'd made before, and consolidated the time to drain oil pan and oil filter can as separate steps, so total time dropped 2 minutes... no big deal!. But I've now grouped the time segments to show prep, drain oil, etc. thru clean-up and put-things-back time.
Stage Time, min. % Prep 11 12.9% Drain Oil 11.75 13.8% Remove Filter 8 9.4% Install Filter 7 8.2% Fill Oil 7.25 8.5% Checks 5.25 6.2% Cleanup 35.1 41.1% Total 85.35 100.0%

Of the 1.5 hrs, 40% (35 min) is just clean-up and put everything back time. The actual work, excluding prep and clean-up is less than half the time or only 40 minutes max, and if I use 20% as an estimate of my liberal time allowances then the actual probable time to actually change the oil and filter work is about 32 minutes. Not that prep and cleanup aren't required, but these times would not apply to a Jiffy-Lube or mechanics shop since these would be done at start of work and end of work day... therefore allocations to a single vehicle would be near nil.. 5 minutes perhaps if I'm liberal. So in reality the most that can be saved by doing it yourself is roughly 35 minutes labor x $80/hr 40 minutes or about $45 max... but for that savings you also get the benefit of the near priceless value of knowing it was done right.

a. Crawl / slide from under engine (0.25 min)
b. Wipe off oily hands (0.25 min)
c. Get 6 qts new oil from where-ever it was stored (2 min)
d. Get long handled screw driver & flashlight or work light ready (2 min)

a) If so, press with screw-driver tip to determine if it's brittle or still has some give to it - 0.25 min
b) If brittle (i.e. hard as a literal rock), remove it; then order a new one & bottom seals too, from MB)
c) If not brittle (i.e. not as hard as a rock) with a bit of give to it be happy
--- you can breath out now.
d) If it's not there
, look in bottom of oil filter can for it...
i) If its in the bottom of the oil filter can, see 12.b above
ii) If its not in the bottom of the oil filter can
:'(, pray your engine doesn't need an overhaul, refer to 12.b above

Assuming bottom filter can seals and top donut seal are still ok, or that they weren't and after being pissed off, swearing at your wife, and getting over your it, you've replaced them:
20. Place new filter can 0-ring seal in lip - 2 min
21. Crawl / slide back under engine with - 1 min
a. oil filter can with new oil filter inside
b. bolt with new bolt washer
c. 17 mm socket,
d. 13 mm socket,

leave both sockets under car for now) - 0.25 min

26. Remove oil filler cap from top of valve cover - 0.25 min
27. Open new qrt of oil, pour into valve cover (6x) - 6 min
a)
CRITICAL STEP: While 1st & 2nd qts of oil are filling, check under car for oil leaks -- I don't know how often someone forgets
to have replaced &/or tighted up oil drain plug before they start pouring oil into the engine. This is no lie.
28. Replace oil filler cap - 0.25 min.
29. Check (look) under engine for drips & leaks (assume none
--- good job
tightening oil drain & filter can bolts) - 0.5 min
