I've had fairly good luck so far with Prodisc CDRs (I have some MIC Verbs that are Prodisc).
But from what I've seen in the UK, I don't think much of the Emtec brand. So, if you can get the Verb DataLifePlus for the same amount of money, I get the Verbs.
Edit: and as for Sony, I have some that scan pretty well, but I bought them awhile back, and so can't tell you much about where they were made, or the spacer. I still have them in their original cakebox, but alas, that's at my mum's place.
