Live at Eindhoven is pretty hard to get and it wasn't released on CD (as far as I'm concerned)- some used vinyls do occur in second hand music stores and on ebay every now and then.
As for RTTAC- I don't know where you're from, but I see plenty of them in music stores here in Poland and have seen quite a few abroad as well, so there probably is no need to even look for them on the Internet.. on the other hand, since you're writing here, you might have already had some problems finding them where you live. I suggest you try harder- they're there.
