I'd spend it on film, and the chemistry to develop it. Having all the kit in the world will not improve your photography. Making photographs will. I had an old Minolta Autocord with an 80mm fixed lens for the first 15 years of my photographic life and shot as much film as I could afford. I also had an enlarger of dubious vintage with a very old Wray Supra 105mm lens and the lot cost me £25, £10 for the camera and £15 for the enlarger. I was given good advice by two old photographers, one said use your camera until it becomes an extension of your mind and hands, the other said photograph the light not the landscape.
Whatever you choose to do enjoy it and I wish you success.
