My first five years of homebrewing were 5 gallon batches of extract with steeping grains, using a partial-volume boil for most of that time. At the time, three-vessel brewing was the most visible all-grain method available by a long shot, and due to space and finances I very much had the impression that all-grain brewing wasn't in the cards for me. I discovered batch sparging around 10 years ago, and that (along with moving into a larger place) helped me make the leap. I have been brewing with an all-in-one electric system for just over four years now.
If I were to do it all over again, or if I were to make recommendations to someone interested in the hobby, I would still recommend starting with extract!
