I think it is very locale dependent. Around here, it is super easy to find foreigner. But there it might be different. There's something to be said for holding out for best condition. That way, you will reallly know what you have in your collection. But then again, during that time, you will be going without. I guess it is a factor of where your tolerance for noise is. For what it's worth, I get great results using Spin Clean! No affiliation, just a satisfied customer. Yes is another story. They are a progressive Rock band, and as such, had a more limited following of their music. I saw them in my youth and it was phenomenal. It is one of a few times I've seen the synergy of crowd/performers. It is a powerful thing never to be forgotten! So Yes is a little harder to find in good condition. Again, locale dependent. Ottawa was a big Prog rock city, as was Montreal, only 2 hours drive away!
