>>3602731Getting a sous vide to regulate a temperature via a water bath will pretty much prevent any fuck ups. Label your bottles correctly and don't mix up the chemical order and you'll have no issues.
>>3602849Assuming you're only scanning 35mm, this will save you SO MUCH time and headache. If you can't afford ~$40 you probably shouldn't be shooting film to begin with.

~$40 from Freestyle Photo.
Arista Premium reels. They have large tabs that makes loading film a fucking breeze. Been using them for a very long time.

A graduate cylinder for measuring chemicals. A dollar store one is just as good as a $20 one from a film supply shop.
~$2
A sous vide that can do 30C temperature. The FPP Heat Helper seems decent and is what I would've bought had I not already owned a sous vide.
$70 from Film Photography Project
Now all you need are contains for chemicals. I use 1L water bottles that I buy from the store for $1/ea.

I can't help with scanners since I scan with my mirrorless camera. IF you own a good digital camera, buying a macro lens for it and using it as your scanner is by far the best option. Avoid Epson flatbeds as they are unable to give adequate 35mm scan quality.
