I have to update this thread.
* It turned out to be a really usefull thread for anyone considering buying a SS machine with some great experience and advice given by quite a few members.
I scored the machine that Blair purchased (mentioned earlier in this thread) and it was a PHOENIX 1978 model by Williams.
I actually really enjoy the audio of this machine, and find it alot better in person than the youtube stuff. So I did score my first ever SS and I enjoy the basic play n feel of this machine. The colours are outstanding, and I love the old school style displays.

I have started a "resto" thread mentioned below.

Next SS will be one of the ones Nino previously mentioned on the thread for me. A big thanks for the great advice guys. SS machines definately rock for sure.
