"like i say, the comp waits on me much of the time anyway, OC is in it's twilight years imho..."
Quite the contrary, I'm of the belief that there is a current golden age of overclocking similar to the Celeron 300A days. Anybody can pick up an Athlon XP
Barton 2500+ or Intel P4 2.4C and run it at stock voltages and get quite the overclock (often with the stock heatsink, though I usually recommend a Zalman CNPS700Cu for noise purposes). Besides, there is usually a good time during any fab process for overclocking. Determining when that is takes experience, or some poking around the right Internet forums asking those who have it.
Maybe it's just that this is all so second-nature to me (I've been building systems for 20 years and overclocking for 19), but I never viewed it as a hassle. OK, so soldering in a new clock crystal was a bit of a hassle. But it was cool to have the fastest 8088 in the land.

Nowadays, though, a BIOS tweak or two is all it takes. Easy...
And sweetnubs, I would choose the same components for a mildly overclocked system (i.e., a 2500+ at 3200+ speeds or a 2.4C at 3GHz) that I would for a non-overclocked system anyway. I never buy marginal components. So there is no cost differential. Now, if I'm trying the uber-overclock so I can go brag on some OC forum, that's perhaps different.
As you well point out, stability testing should be done irrespective of your choice to overclock or not (at least for DIY systems, OEMs ostensibly do that kind of testing for you).
BTW, I'm not trying to evangelize here. As I said before, to each his/her own (especially when your livelihood is on the line). I just think that people should be informed what their options are, especially for us home recording hobbyists who don't have large budgets(not that comercial studios necessarily have lots of money to waste).
