My favorite cloth diapers are the prefolds from Changing Times Diaper Co (same construction and fabric as those sold by Rearz). They are, put simply, adult-sized baby prefolds. The manufacturer (Ashar in Pakistan) is the same one that makes the ubiquitous Green Mountain baby prefolds, and several other well-known brands. Good stuff. Changing Times also sells plastic pants and other waterproof covers, which are a necessity for most kinds of cloth diapers--except for pockets and AIOs. For pins, I use Dritz-brand baby diaper pins, and have found them to work very well.
Baby Pants diapers, like the one you linked, are also available from the Baby Pants web site (baby-pants.com). Like Changing Times, Baby Pants also sells plastic pants, pins, etc. Their prefolds are probably my second favorite. If you go the Baby Pants route, definitely go for the twill weave or the gauze weave. The Birdseye, at least in my opinion, has a somewhat unpleasant texture. But then I'm picky that way.
Tetra mentioned Angel Fluff. I haven't tried their fitted diapers, but I have to say that I don't much care for their prefolds--very thin and very expensive for what you get. I have to wear two of their nighttime prefolds to achieve the thickness of one Changing Times prefold, and it's not like the Changing Times prefolds are super bulky or anything. Some of the other Angel Fluff diapers are flannel, and while I haven't tried them, I *have* tried the Babykins flannel prefolds and concluded that flannel just isn't a great diaper fabric. The tight weave hurts the absorbency, and makes it difficult to use alternative fasteners like Boingos and Snappis. You'll notice that very few actual baby diapers are made of flannel, and there's a reason for that! The only things it's got going for it, IMO, are that it's available in prints, and that it's ultra cheap--which, I suspect, is why the North American adult diaper makers use it, and is also why their sky-high prices are so hard for me to justify. In short: I've found the imported diapers to be almost universally superior to the "domestic" diapers, while also being much cheaper.
AdultClothDiaper.com sells USA-made gauze weave diapers, though, and I think those are alright. The stock dimensions are a bit long and narrow for my body type, but custom sizing is available for more money. My only real aversion to AdultClothDiaper is that the gauze fabric doesn't quilt up like some other gauze weaves do, and I have a real "thing" for that quilted texture. Functionally, they are fine diapers.
As for folding: If you go with prefolds, look up "angel wing fold", "newspaper fold", and "jelly roll fold", to name a few. Folding and pinning is old-school, but I like it. A little practice is required, but then taping disposables requires a bit of practice, too.
