Despite having a bin full of these, I am seriously considering one of the new ones for my upcoming Hillibike.
Rich, if you enjoy working on bikes, I would say definitely worth the time and investment, especially if you have never worked on a classic cup and cone bb. The couple of folks over on iBOB who have received theirs have remarked on the high quality.
The basic tools are not all that pricey. I'll bet you could pick up a good used set on ebay.
I think The Cup & Cone would be an excellent name for a "bike cafe" except that it could be confused with an ice cream shop. Too bad, that. Maybe The Cup, The Cone, and the Scone?
