"Cool factor" aside, are these really worth $225 over a bucket with a spigot?
That's a "Is a Ferrari worth $200k to do 65 MPH on the highway" kind of question. If you have to ask, it's probably not for you. Once you understand/appreciate the finer details, if it's something you want, you will just buy it. Assume that statement applies to all homebrewing hardware.
If something is truly a pile of suck, you can be sure there will be near unanimous agreement on it. Otherwise, it could be good or bad depending on what you were looking for and what your personal value system is like.
