Denis,
I buy my Sound Choice in Toronto because I'm there once a month so my favourite place is Laserland which has good prices.
They come on promo sometime for $30,00 but in general I pay around $40,00 CDN of course!
They do ship by courrier and they're very efficient, the web site is
www.laserland.com The best thing is I get to listen to them before buying!!
I just purchase a disk that has Suite Madame Blue and as far as I know, sound Choice is the only one that has this song. I got another version from All Hits but what they did was cut & paste from the Styx version with terrible result!
This version sounds better than the styx version because todays equipment is superior than the ones use 25 years ago.
I also got a disk with Elton John's music and I can't find anything better from any other company.
Another good brand would be Chartbuster, check them out.
Have Fun,
Salut
