Hm AE1 discs came from a store that branded them as LG dvd-r. I only got them by luck.
But the E01 are also great and cheaper than anything I’ve seen anywhere in Australia (for top quality media). PCX has them for a nice price of 17.50 per 50 if you buy 6 or more spindles. Otherwise it’s like $22 per spindle I think, which is not bad either.
I’m not sure what you mean by older scans with E01 and AE1? I’ve only really used them this year. If you are wondering about how stable they are over long periods of time, there’s nothing to worry about, they have been reported as very stable discs by many users.
I won’t tell you not to get the MCC02RG20 though, they are great discs and are very stable and compatible. The only reason I’d get E01 is because they are crap loads cheaper and burn very well.
If you get some MCC02RG20 off PCX, it may be a good opportunity to get a spindle of CMC E01 while you’re at it
