Spending $200 or more on a mixer to *start* making pizza is a big outlay of cash. I would suggest your first purchases should be a baking stone and peel. Make the first few pizzas by hand. Once you get a few under your belt, then think about buying expensive appliances.
Hand kneading dough is not as daunting or time consuming a task as you have been led to believe. For pizza dough, in less than 10 minutes you can form a fully developed dough. It is a lot less messy than high hydration artisan bread dough.
For pizza dough, you can go from ingredients to dough in less than ten minutes - by hand.
I am a member at HomeSpunPizza.com (membership of $35 required). The pizzaiolo/teacher there is Bubba (he's a member of this forum). On his site he has video demonstrations that take you from pre-measured ingredients to fully developed dough ball in about 7 minutes, for each of three methods - Kitchen Aid mixer, hand mix in a bowl, and hand mix on a bench (counter). In each case, it is just 7 minutes or less from ingredients to finished dough. And yes, that is 7 minutes - by hand.
I would recommend his site for people learning the basics of dough handling, and for those trying to decide whether they want to drop $200+ on a food processor with the guts to do the job, or a stand mixer like the KA or DLX.
You have to join his site, but for $35 you will learn how to do it by hand possibly saving yourself hundreds.
For those just starting out, you can learn the basics then move on to perfect your own style, try different techniques, and make informed equipment decisions.
For the record, I'm not affiliated other than me paying for a membership at his site. I wrote a longer review in the Cookbook Reviews section of the forum:http://www.pizzamaking.com/forum/index.php/topic,3762.msg35738.html#msg35738
My advice: Start simple and cheap, get informed first.
