123.450 is commonly used, but that frequency is already allocated to a specified purpose, and you may severely p**s off some people if you use it in certain areas.
This subject has come up before in the threads, and an experienced Air Traffic Controller on here suggested that, although still not official, 123.4 would be a better choice, as it was not, to his knowledge, assigned to any purpose at present.
