I've not seen any magic about it's price either.  It's pretty much right 
in there with the Belden cables.  Compared to the early days of 9913 
it's really cheap..er inexpensive at about half the price 9913 debuted for.
I use LMR-600 particularly on 160 and up in the VHF plus range.  I use 
it on 160 for the low resistance and for the low loss on VHF and up and 
again it's relatively inexpensive.  Most quality cables give a projected 
lifetime of 20 years.  The LMR-UF versions only give 10.  I managed 6 or 7.
