Electric tillers are available in a wide price range. The heavier use gardens might benefit from a better tiller, designed for longer use. But, for a small garden electric tillers can be found at reasonable prices.
Remember, the wider the cut the less walking for the gardener. That having been said, a wider cut requires a motor built for a greater load. For my purposes a foot wide cut is fine. And a six to eight inch depth is enough, since I plan to add garden soil to the tilled area, thus building it up. So, even a long carrot would thrive with an eight inch tilled bed and four inches of added soil building things up.
Less than six inches might in insufficient for removal of some deep rooted grasses. The depth need be sufficient to clear anything that might have a tendency to grow other than what you have planted.
One thing you must decide is whether you want two handles that are disconnected, or a bar connecting the side handles. Think about a wheelbarrow, and how you grasp the handles. The hands are at right angles to how they would be orientated pushing a crossbar. Which is more comfortable? Also to be considered is that the separated handles do not have to be at the same height when making a turn, which might make turning easier. So think about how often you will make a turn.
Another consideration is the availability of electricity. Think whether a long extension cord will reach from the nearest outlet. If not, or if you are careless and might run over the cord, cordless models are available, albeit with fewer choices.

You are right to use a mixture of techniques to cultivate your garden.A tiller plus weed mats seems a good idea.
Thanks. Frank, your input is welcomed. I plan to use a garden mat to assist in blocking weeds.
This is an interesting article on an aspect of gardening that has not been covered before on this site. A word of advice. Certain weeds that spread by rhizomes, such as couch grass, are made worse by being chopped up, as a new plant can spring from each bit. So before you use the tiller, try to get rid of as many perennial weeds as you can. You will not regret doing so.Get them up by the roots, it is the only way.
I might consider getting one of these as we need to make some raised beds this year. An electric one sounds good.
