Many machines from perhaps 10 years ago will be perfectly running at the seller's site, but will not come up at the buyer's location, even though they were professionally rigged and moved. Connections work loose, etc. Don't ask how many people have had this happen, the stories are legion. A good tech can probably get such a machine running again in a few hours, but these older controls are just not reliable. I had an old Allen-Bradley, and had 3 breakdowns in about 9 months, and got real tired of it. I DO have the expertise to fix it, but just never knew if it was going to fire up any time I tried to use it. I replaced it with a PC control, and have had absolutely minimal trouble in the last 12 years.
