I have two pieces of advice.
1) Slow down.
2) Utilize Google.
In the world of professional breweries, if you ask people that opened a brewery what one of their top regrets is, the answer often given is "We should have gone bigger to begin with". Yes, they regret putting in a size X brewery when they quickly needed a size Y brewery. #2 on the list would be they regret not properly sizing the building to fit their size Y brewery that they now need...
In the world of homebrewing, you'll find time and time again where people buy X, then soon after realize they should have bought Y. Many then buy Y, and X sits in the basement or is sold at a big loss. I know a professional brewer that has an entire storeroom at home full of homebrewing equipment demonstrating his impetuous nature.
While it's fun to race forward, unless you're made of money you should slow down and read more. There is a ton of information out there. Then, when you know what you want to buy, research prices, and possibly wait for a great sale.
