I guess if we're not talking ingredients, just "stuff" related to brewing, I'm probably around 2 grand. I built a keezer last spring, that when all was said and done, probably cost me around a grand for everything. By brewing system is really pretty ghetto- Turkey fryer and cooler for outdoors, and I also do indoor stovetop small batch ag brewing often too. But I just have accumulated a lot of "stuff" over the years, to aid in my process, and made a bunch of things.
I have probably a dozen fermenters of various sizes for instance. I have a 5 gallon oak barrel. I have a refractometer, I have probably a half dozen or more thermometers, 3 hydrometers....I have three autosiphons. I have three ebay temp controllers, one on my keezer and two wired modules for temp control of fermenters (and even when I cook sous vide) I even have a couple coffee urns that I use when I'm doing stove top ag to heat strike water that I got from the salvation army, that sometime I'm going to turn it into a small batch rims or herms system.
For years I always bought brewing stuff for myself for Christmas....But this year I couldn't really come up with anything that I felt like I really needed or had to run out an get, though I want a floor corker for wine and champagne bottles and probably down the line a ph meter, (but I haven't played with PH in all these years, so it's not a priority.)
Actually this year my gifts to myself have been all Chracuterie related; a bunch of little odds and ends to cure meat and make sausage, I just for example picked up from Granger on my way to work a humidity controller, just like an ebay temp controller but it fires a humidifier when it reaches a certain set point. I also bought a cheap ultrasonic humidifier to hook up to it, and a hygrometer. Plus a bunch of plumbing parts and a larger aquarium pump for a cold smoker.
