I like the power rotary tillers for quick work, but my area isn't that large, and I don't believe in ongoing tilling with them, only an initial tilling. Doing so repeatedly over time builds up "hardpan" and that restricts drainage and root penetration. I prefer to hand dig (great exercise) and double dig the bed. Afterward, with additions of lots of compost and mulch, it becomes a lot easier.

I'm looking at a tractor down the road, but haven't had the need so far.

Have a post hole digger and some spades/hoes, but need more durable ones. I really don't see the need in the specialty equipment you listed, at least not at the level of gardening I do. I just have a "kitchen" garden, not a farm.

The garden I normally work is about 100 ft by 250 ft, and that's barely enough to feed a family of 4.
Get an old tractor and learn how to maintain it.
Even if you have to completely rebuild it, you never regret it.
Then there's tractor shows you can go to.
Watch RFD TV.

"I don't believe in ongoing tilling with them, only an initial tilling."

When the sun gets hot and the rows get long, a tiller can knock down a lot of unwanted grass and weeds in a hurry.
Then just take the two rakes and clean out the loose weeds and grass.
The narrow rake is for between the plants.
