I know that i have recieved very good advice!
I was offered a twilight zone for what i thought to be cheap. I saved my money, but when i checked it out it was missing some parts that i was unsure if they were readily available or replaceable. I thought that if anybody would have one it would be Markc.
SO a cheap twilight zone is worthless or not worth it without the parts to get it going. Oh well.
I'll just have to keep working hard and saving my money until the right machine turns up.
Thanks
