Right now I'm using the Vitamix 7500 blender which is great. It pulverizes pepper seeds and anything I put into it. But it has a 64 ounce capacity. Is anyone using a larger capacity blender – 1.5 gallons or more? Vita mix makes an XL – 1.5 gallons for $1550 but I don't know much about it and it is critical that seeds disappear in the blending process.
