I have gone from shaking the beer in a carboy/better bottle to using a big paint mixer for drywall mud to an oxygen stone/bottle kit. The stone is obviously the easiest. It's highly recommended because a lot of research say it can get 8-10 ppm dissolved oxygen within 1-2 minutes. It was inexpensive for me to buy used so I thought I'd give it a try. While I've only used it for two batches I can say I like it simply because it's easier. I've had stuck fermentations on other beers and this seems to eliminate that. I also use 1.5 L starters, save .5 L for cost savings, and currently pitch at fermentation temperatures. I'd either ask for an oxygenation kit for Christmas, gift it to myself, or keep an eye out for a used one because it's less work and pays for itself, in my opinion, after one batch of not needing to shake XX gallons of wort (depending on how big of a batch you brew). It's just my opinion but I'm happy with my choice to go with red oxygen tanks.
