I started brewing at the beginning of December. I have 8 batches in.
My suggestion: if you think that you're going to be in this for the long haul--and if you're already want to place an order for more ingredients, then consider purchases that will support a greater commitment down the road.
In my experience, whenever I try to cheap my way to something in a hobby, I almost always regret it. I end up buying the better quality/greater capacity/easier item later on, and regret the money I spent on the cheap item.
It's sort of like buying a gun safe--they always tell you that you should buy the next size larger than the one you think you need. And they're right.
I knew I could get a cheap Corona mill but also knew that I'd wish I had a better model (Cereal Killer, Barley Crusher, something like that). I gritted my teeth and went one better.
I know also that when funds are short, they're short. When that's the case people often buy the cheapest stuff they can get by with to see if they really want to continue with the hobby/passion.
I suggest you do two things: first, become friends with Craigslist. Search on beer, brew, and brewing. There are occasionally people getting out of home brewing and they sell off their setup for very reasonable prices.
As an example:
https://iowacity.craigslist.org/for/5531097277.html
If you're not nearby that isn't so valuable, but there are people all over selling off parts and pieces. I'm looking at that 10-gallon brew kettle and thinking it might be worth a drive for me (it's about 75 minutes away). Plus anything else he has.
I found a guy selling out (small kids, no longer has time) who sold me a refrigerator, mash tun, two carboys, fastrack bottling racks, InkBird temp controller, 5-gallon kettle, bottling bucket, a bunch of 22-ounce bomber bottles, stainless spoon, hydrometer, and a bunch of other odds and ends for....$150. I sold the carboys for $25, so my net was $125. For stuff that probably is worth $400. Craigslist: worth a look, and keep at it.
Second, have patience. Items go on sale from time to time at online retailers, and you can save significant amounts (20 percent or more). A kit
like this for kegging is not, IMO, all that great a deal at $149.99. At $120, though, it's a better deal.
Good luck, welcome to the obsession, and brew on!
