I have the "Vitamix Standard Blender" that I brought through Amazon. It is "Certified Refurbished," which saved me some money. It is the same model as the 5200. It is two years old now and it has served me extremely well.
Mine just says Vitamix Professional Series on the front. My first Vitamix lasted over 10 years. I bought this one about 5 years ago. I noticed that they are selling them at Bed Bath & Beyond so you can use a 20% off coupon.
Best wishes for a successful procedure. My brother's best friend lives in The Villages. Is Marixa your ALSA representative?
