I think it's also one of those things (as far as pizza is concerned) that is just like flour in that you eventually come back around to where you started... People on here (myself included) may have spent months trying various types of flours and protein levels and grinds only to realize you can make perfectly good pizza with store brand all purpose if you do it right (and this flour is probably still better than what some of the greats used 100+ years ago). I have had great pizza from all types of mixers, from someone's own two hands all the way up to 5 figure specialty 'kneading machines'..
I agree that a Mixer does not run a Pizzeria. I was referenced to a Screwdriver earlier in this post, and how well it made Pizza. The issue is that I don't own a Mixer. I'm using my Wife's Oster Bread machine and it's going to die a premature death from mixing Pizza dough. I also don't have any control over what it does and how it does it. So, I want to buy a Mixer, and I'm an Engineer so I was doing my research. I don't buy anything without looking into it beforehand. I would not Pay $1800-$2000 for a N50, so I started watching Sales like Ebay and Craigslist.
Here were my requirements that I started with:
1) Handle Bread dough and Pizza dough up to about 3-4 Pounds with little or no strain
2) Be able to sit on a counter top
3) Cost around $400
4) Be good at mixing
5) Be a Lifetime Purchase
The KA's in my research failed 1 and 5.
Before I started the research, I wanted a KA 6 Qt pro. I thought Kitchenaid, what could be better, you see them everywhere. Hell, even MARTHA uses one. As soon as I saw the first posting about straining with anything thicker than AP flour, I started looking further. It finally came down to the DLX and the N50. The DLX finally lost because of a few comments on this Forum about them and the CI review. I also talked to the Engineering dept at Hobart who test all mixers and asked them questions about Vikings, Bosch's, N50's etc.
So it came down to the N50.
The last thing I would note is that anyone with a KA of any Vintage should be in Love with a N50. Can't you see the family resemblance? It's like saying your Grandpa sux! My Grandpa may not be as Svelte as he used to be, but he knows a lot more about the world than I do.
As was stated somewhere else, the Hobart N50 is what a KA want's to be when it grows up!
There is a consensus that when Hobart Sold off KitchenAid that their quality and reliability suffered.
