Blender Dilemma

Here is the story of my blender Sega from the past couple of years. Since we have been in North America we have gone through at least five blenders. If you are a true smoothie lover you know how hard it is to get a blender that will stand the test of time. I have even had a smoothie blender and it did not last. In the picture you will see three of the blenders we have owned in the last couple of years. The motor went on the white blender. The blender that is upside down is under a year old and has been replaced once. The motor on that blender was great, nice and powerful. The problem came in when you go to make smoothies and the blender has so much power it actually melts the bottom part which makes the blade actually blend things. So after it breaking twice in a year, it is not worth replacing it again to have the same thing happen. Well, after a bit of research I just bought another blender. Like I said, we do like fruit smoothies. The blender actually has a metal part on bottom so I am HOPING this one will not melt like the past one did. Will this blender stand the test of time? I am doubtful but willing to once again try out yet another blender. If there are any smoothie drinkers out there that have found a blender that works, and that isn't too expensive I would appreciate you passing on the make and the model of a blender that stands up to for true smoothie drinkers.
