Trouble with blenders, is that not all are the same, even medium priced ones..
You HAVE to check reviews and find a good one on sale, or with a good offer... Maybe package deal?
There are places to buy industrial food equipment for normalish prices (procook is one . They're online and at some retail villages (in the UK)).
Also worth going direct.... Write a nice email to the CEO (CEOEMAILS.COM they list CEOs for almost all companies around the world) explain how much you like their stuff and want to buy something..
