I made a post up in the Teknetics forum and guess i should of posted it here instead.Got some of my questions answered and thanks to those who replied.Anyways here's the story,was at a local flea market and picked up a Teknetics 9000 the one with the LCD display,the machine is very clean and powers up nicely and everything seems to be ok,now i took it out the other day and for some unknown reason it didn't seem to want to GB right or maybe it was just me,don't know.Anyways should i keep this machine and maybe send it into Kieth Wills [sp] or is it not worth the time or am i maybe just doing something wrong?It's really a nice looking machine for as old as it is but maybe not as good as the A/B models.Rich
