I have that one and don't like it at all, well, it's ok.
I bought that one when the didn't have the hm12.
A comment on the bandwidth of radios. Even thought they may not
take advantage of the mic ability, the quality of the different studio mics
will still be noticed over hand mics and some differences in studio mics.
The quality of the elements will help.
I can whisper in my Shure SM7B as low as I can and hear every syllable in
the sentence. I can do the same with the stock hand mic and it's not a clear.
Same with my Heil PR781 and the GE-5.1 Even if I narrow my radio down I can still hear the difference.
Money, toys, and play, it's all relevance, right. 
Have fun with what ever you try.
