All this nonsense about how Mac's memory is somehow special etc is just total nonsense. RAM is made to specific standards and timings, if the specs match and the product is not faulty, it will work, period.
I picked up some DDR2 RAM mail order from NewEgg (Kingston I believe, 2 1 gig sticks) and it works just fine. Yes, there is cheap RAM out there that is crappy construction-wise but if you stick with reasonable brands and you purchase the right spec RAM it'll be fine.
Your problem here is that you never get to see all the specs. Therefore you can never tell by looking at it whether a given piece of "PC3200 184 pin 2.5V CL3 DDR DIMM" conforms to the specs or not.
Specifically, the row and column and rank organization of the chips, and the Serial Presence Detect settings on the module are important. You wil never, ever see these published, so you have to rely on either the seller having tested and guaranteeing compatibility, or trust to luck and do your own testing.
Different Macs have different tolerances to RAM that is not programmed correctly in the SPD settings. RAM that works in a PowerMac G5 can fail miserably in an iMac G5 or a Mini, same story Powerbook 1.5 GHz vs Powerbook 1.25 GHz. The nastiest scenario is where you have marginal RAM that works OK under 10.2.8, but fails when you upgrade to 10.4 because 10.4 introduced tighter conformance to the specifications.
I am glad your purchase worked out for you. But it is incorrect to extrapolate that to all models Mac or all RAM with the same nominal specifications.
enkwanzer: OWC's RAM is mostly lifetime guaranteed, their other products carry the manufacturer's normal guarantees.
"After 30 days from the invoice date, item is subject to Manufacturer's warranty"
A few people
here on MR have commented about OWC holding to their 15% restocking fee when returning goods that didn't work.
