Best investments I've made to ensure I enjoy the process I'd say is temp control and kegs. Manual temp control can be stressful and bottling can be a real grind. Itndoes require a couple of fridges to suite or, alternatively, a couple of mini kegs you can refill from a 19L corney and dispense thought a party tap and a mini reg. That would probably be regular fridge friendly for dispensing at least.
If I were to start again I'd probably do things differently. Skip kits and go to full volume extract to start with. Would let you buy an urn or RB off the bat and get in to all grain in a couple of stages. Then use residual money for temp control fridge using 25L hdpe cubes for fermentation with a blow off tube. But that's based more on where my own process has moved to, so ymmv.
