I considered getting one, but when I took a closer look I realized I wouldn't need something to grind grains or cook hot soup. What I wanted was a blender that wouldn't choke, no matter what I put in it. I chose a Breville Ikon Hemisphere for around $200 (currently $166 on Amazon) and I think it's amazing! Almost everyone that has seen mine in action has bought one as well.
We had a $20 Hamilton Beach at work and it was fine for banana smoothies and maybe a few cubes of ice but choked on hard frozen strawberries. It also required stopping to scrape larger bits of food from the sides. (I should also note that we threw it away after we became spoiled by the Breville)
My $50 Oster Beehive, though very loud, was much much better but still retained a few chunks of frozen strawberries and required occasional scraping.
Breville - Anything I put in it is instantly liquefied into the most perfectly smooth mixture you could hope for. It's quick and I don't have to stop midway and scrape anything down. It has a unique blade configuration for more thorough blending and I really do notice a difference.
Good, better, best. I'm sure the VitaMix is better than the Breville, but how much better and does it equate into a couple hundred dollars more? It really depends on what you plan to do with it when you get it home.
I know there are quite a few Vitamix owners here (topic has come up before) so hopefully they will pop in with their opinions after having had it a while. If not, a forum search might be helpful.
Please let us know what you choose and if it lives up to your expectations
