I have the annular cutters from the links posted, the Kimball is US made and comparable to the Hougen, he also sells a larger set, the major limitation is the 1" DOC. I have seen some sets that come up in various sizes, I would say it is a waiting and searching game to find what your looking for without busting the bank. In particular on the larger cutters, they can get pricey quickly. My limited experience in using them, I would say they are preferable over conventional drills at 1/2" and above, you also do not need to drill sequential holes to remove material. The hole finish is also much better than hole saws. My concern would be stability when using much larger annular cutters that have a stub shaft.
Holders, they are also sold by some US vendors:
