propane pizza ovens are GREAT for parties and whenever you need more than one pizza every 30 minutes.
Otherwise, just use a baking steel in the top 1/3 of your oven and a full-sized ceramic pizza stone (one that covers the entire oven rack) in the bottom 1/3 of your oven. Crank it up to 550 degF (usually the max for prole ovens), let it preheat for an hour, and cook your pizzas on that. You need to let it reheat 30 minutes between pies.
You'll get near-perfect pizza every time. I have been doing this for years and now my friends and whatnot actually prefer my pizzas over anything in the area. I also use extremely high-quality ingredients (e.g., ezzo cup & char pepperoni) and a cheese blend that's 50% whole-milk mozzarella and 50% part-skim.
