Radwell is an absolute joke if you want to sell anything. I had a virtually new Controllogix L72 processor and they offered me $375.00. Looking at their website, they sell them for $4500 dollars. They called me several times and I told them I wasn't interested in selling for that price. They went on saying they didn't really need it anyway because they had a 3 year supply. I would rather donate it to the local college then sell it to them for $375.00. They used to be better but maybe they have gotten burned in the past.
