If you are just looking for a starter kit, I personally would get the deluxe brewing #1 seller kit. Two carboys will last you a long time, the bucket forever. Heck, I still have my original capper, carboy and bottling brush, my siphon lasted a decade, and the bung and airlocks with last you a long while.
As for the mini fridge, remember the compressor is on the bottom, you will need a tall mini fridge. I recently bought a chest freezer for $60. It can hold two carboys. I recommend and inkbird controller.
That brewmaster kettle was pretty nice.
