I bought my Advantium from a scratch & dent dealer, no less, new, with a small dent and no box for a fraction of the retail full price.  The interior light went out before years end, and G.E. promptly sent someone out to fix it and have never had a problem since.  I have always used it multiple times per day, with using the Convection feature 3-5 times per week.  I have the 120v but it microwaves as a high power microwave, so quick times.  The convection is absolutely awesome and I could just not be happy without an Advantium microwave.  Best fries, baked potatoes, chicken tenders, battered fish fillets, etc., etc., etc..  I did almost forget to mention, my the underneath lights that give light over my stove did go out last year, but that is small compared to the use and value, and simply easy and delicious food I have got out of this oven.  It is one of the best purchases I have ever made.
