Personally, being retard and a cheapskate, I can't afford and wouldn't pay that kind of price. You can find much cheaper ones that do a great job on Sharz or Grizz or other cheapo places, but yes, that type are the good ones.
Be careful when you buy this style, however, in that there are several sizes: AXA, BXA, CXA and maybe others. These letters (the first letter A, B, C) indicate the size. (THis took me for ever to find out what those mean). Essentially, the A size is for small machines and certainly not suitable for taking large cuts. The B is medium sized machines and quite suitable for large cuts. The C is for large machines and suitable for huge cuts.
So if you buy a "B" size, all your tool holders have to be "B" size. You can also make some, they aren't too difficult. The 60deg. inside bevel being the most difficult and care has to be taken to get them spaced correctly. There is also a trick for making them where you don't need to be quite so careful.
