Well, isn't there a mid-grade radio between "entry level" and "contest 
grade"?  I consider entry level to be the Alinco or the ICOM IC-718, 
both under $1000.  For $1500, I wouldn't expect a super contest radio, 
but I would expect something better than entry level.  (Ah, when I was a 
boy, entry level was a used Hammarlund receiver and a Heathkit DX-60A).
