Sort of... Citizen makes one that is similar, but I can only find it at RapidLED (and their sister sites) that should prove pretty good-

At four times the price (nearly) I haven't been in a hurry to grab any, especially considering that outside of rapid/menari or COBkits I can't find any sources in the US that stock them. If the quality is like the other chips from Citizen they should be a great choice though.
