Query: Big Mistake

I think this is a great idea, and thats all. I bought the 250 and had nothing but trouble with it. After 5 hours on the phone with customer support, I decided to take it back and get a refund. I ended up buying the mailstation 120 and it has been great, no trouble at all. This was a gift for my elderly grandmother, and she has used it almost every day since, and she loves it!!
