In reply to Chris Tropea :
Here's what I'm using for developing; AP developing tank (Arista branded, you may find this for a better price elsewhere, I like this tank and reel setup), $40 - https://www.freestylephoto.com/5042-Arista-Premium-Single-Reel-35mm-Developing-Tank-with-One-Reel
500ml beaker - $10 from anywhere - used for mixing water + developer before dumping into the tank
10ml graduated cylinder - $10 or less from anywhere - for measuring liquid developer accurately
Developer - Legacy Pro L110, pint - $17 - basically a copy of Kodak HC-110 but more like the old formula which lasted a long time on the shelf after being opened. This is a pint bottle, I use 5 ml to develop a roll of film, there's almost 500 ml of liquid in a pint. So about 100 rolls of film worth of developer using HC-100 Dilution H - https://www.freestylephoto.com/10190-LegacyPro-L110-Liquid-Film-Developer-1-Pint-(Makes-2-Gallons) - Something to note, I mix this developer on an as-needed basis for each roll. Kodak's suggestion was to mix this stuff up a gallon at a time, but that will have a shelf life of a month. I see no advantage to doing this that way.
Stop-bath - "Free" - I just use tap water as a stop bath and it seems to work great. This is commonly done.
Fixer - Clayton RF19 Rapid Fixer, quart - $12 - probably enough fixer for 20 or 25 rolls of film, I dump just a little each time I develop a roll and then pour the rest back into the fixer mix bottle (you mix this with water and keep that as a stock solution, it lasts a long time) - https://www.freestylephoto.com/366191-Clayton-Rapid-Fixer-(RF19)-1-Quart
Wetting Agent - Arista Flow, 4oz - $7 - I use Tetenal Mirasol wetting agent at the end of the rinse at the very end of developing to try and remove water spots. A couple drops and one last tank fill with distilled water and I get few water spots if any. Unfortunately Tetenal is out of business so I picked another brand. Probably last you a decade.
Distilled Water - $2 from anywhere - I mix developer and rapid fixer with distilled and there's the final rinse at the end. Figure a gallon is good for 7 or so rolls of 35mm film.
I use a couple stainless steel funnels and a 1 liter brown plastic bottle for holding the fixer in. Shop around, $10 for all of it should do there. I also hang the negatives from a shower currtain rod using "boot clips" which cost me $7 for a pile of them, you need one at the top and one at the bottom as a weight to keep the film from wrinkling as it dries. These things are super useful in general; https://www.amazon.com/dp/B096RLN1ST?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_2&th=1
Fast math and adding some for tax etc that's about $120. After that it gets cheap, like $1 a roll cheap.
