If you're saying that for these important photos that Samys won't do them justice, what should I look for in a lab? What's a good way to compare, should I shoot some test charts and send them to several labs and see which rolls come back looking best?
Well, I was factoring in the time and repeatability of a professional job. You can't (easily) fly a few dozen people to some little island somewhere (for example) and re-shoot your job because some minimum-wage guy sneezed on your negs. There is also repeatability - if your client wants another series of prints, or something has to match between two shoots a month apart, then going to a processor who doesn't control their chemicals is not going to cut it. Then there are the services which are not straight printing, such as large format inter-neg work off transparencies etc. Fortunately I am not doing professional stuff, so have less stress like that.
Also, having a small lab in a corner-shop does not mean that the results will be all over the place, but on average there will (one expects) be more reliability at a different sort of lab. If you've found a little place that is always good, then why change ? It can even be useful as you can always have a chat with the main worker about not letting the new guy practice on your holiday shots etc.
A few times I have heard that 'professional' labs are boasting of processing C41 in hand-tanks with one-shot chemistry these days. That seems rather bizarre to me, but it is over twenty years since I worked in a Q-lab lab so things might have changed. There are lists of Q-labs available from Kodak, and there used to be a similar quality system by Fuji too (which one was used depended on where you got the consumables) plus there would be word-of-mouth, if you can find a good local professional using film, and you could always post in the relevant forum at Apug with the question.
Really the film costs are a red herring I think. The trade-off is between getting the results you want, whatever they are, and the time and enjoyment you require to achieve them. I happen to enjoy darkroom printing, hence it is not a 'cost', whereas I sit behind a computer all day so wouldn't want to develop square-eyes by using one for my hobby as well.
