Another HRM question...

Hi guys, appreciate you've probably had loads of these types of questions, but unfortunately I've missed them, so here goes....

First off, I'd like to purchase a decent HRM, and have a maximum of 100 british pounds to pay (approx $165 US).  It needs to be easy to use, accurate, and I'd prefer one with a HR belt and that I can upload to my PC.  I'm female, so wouldn't want anything too huge, as despite my 5'8" frame, I have TEEEEENY wrists!  However, the bulkiness is the last on the list of priorities. 

Your feedback would be much appreciated!!
