How much are you guys able to cast and powder coat for?
The big cost question is your source of lead. I bought hundreds of pounds of it years ago, and family gives me some occasionally (remodeling old plumbing, etc).
If you pay $ for it, just do math to get your lead cost per bullet. There's 7000 grains in a pound. You should have nearly 0 waste because all scraps just get thrown back into the pot to melt again.
So for example with 158g bullets, you'll get around 44 bullets per pound. The powder coat paint jar will last a very long time so that's nearly a 1 time cost.
On equipment...
I'm a huge fan of Lee 6 cavity molds. You can go fast with them. Handles are sold separately but you can easily move the handle to whatever mold you're using at the time.
sample hereA bottom pour lead pot helps you go fast, but you can get by with a hot plate and ladel too.

To powder coat I use a cheap convection toaster oven.
here's an example but just get whatever is on the shelf at goodwill for $5.
And a cheap bottle of paint
sample here. I avoid the matte finish powder coat. I read somewhere they put an abrasive additive in it to knock off the gloss. I don't know if that's true, but if so I'd rather it not go down my barrel.
If you'll never upgrade to the bottom pour lead pot, you might be happy with a 2 cavity mold and save some $. But if you eventually get the bottom pour pot, you'll want the 6 cavity mold.
Super low budget start: $70 + lead & paint ($40 for a
cheap mold + hot plate, pan, ladel, toaster from goodwill)
For a little more money, you can probably get going for around $100 + lead & paint ($70 for a good mold & handles, then hot plate, pan, ladel, toaster from goodwill)
Then if you stick with it, look at adding the bottom pour lead pot at some point. You'll still use the hot plate and pan you started with, for doing the initial melt of dirty lead (to skim the garbage off it). A thermometer is helpful not necessary.
Do not use pans ladels, ovens, etc that you use for cooking! lead poisoning isn't something to flirt with.
