Always Trying
This is what mine looks like after about 4-5 years of trying.
Not Pretty but functional.

That's a very neat set-up !

All these set-ups seem unnecessarily complicated in the 21st century now we have digital cameras with accurate shutters that can be used to test film cameras.
Using my Nikon dSLR, it took just 30 minutes to build a test rig and adjust the shutter speeds on my Mamiya 645 (which were off). In addition to the dSLR, all I needed were two books with dark covers, a bit of white paper, a black T-shirt, a desk lamp and some Blu-Tack!
I've since had film developed, and the Mamiya's shutter is now bang on.
These are the instructions I used: http://vapour-trail.blogspot.co.uk/2009/04/how-to-test-calibrate-manual-slr.html
This method seems extremely fast, easy and accurate to me, and doesn't involve building or owning a dedicated shutter tester. I found the peak position in the histogram to be very sensitive, allowing the shutter speed to be set very precisely. Although the website is for testing a film SLR, I'm sure it'll work for cameras with non-removable lenses.
Can anyone see in any pitfalls with this method?

You can also measure your shutter speeds with your iPhone/iPod Touch or IPad, using the Shutter-Speed App, which I wrote. See this topic here: http://www.rangefinderforum.com/forums/showthread.php?t=138039
Together with the optical phototransistor plug, which you can connect to your iPhone, you have a very neat setup to measure shutter speeds, without having trouble with soundcards, microphones, audacity and excel-sheets
