$50, good price for an Omnikey
I love Northgates but this is less desirable because of the layout. The 101 with true-ANSI is the one to have, in my opinion.
The bigass enter is less objectionable with a full-size backspace, but the lack of function keys at the top is a problem for a lot of people.
Personally, I like the left function keys, but it is nice having both.
