I just went through the search for a new HR strap as well. I have the very reliable Garmin (older plastic version that came with my 705 which Kevin posted above).
Sadly, it wasn't working once I got an ICD. The wireless signal from the ICD certainly isn't in the same ANT+ spectrum, but for some reason the HR data was no longer reliable.
I got both the Mio Link (~$85)
and the newer Garmin Premium Soft Strap to see what would work.
The Mio Link worked ok, but if I put in a short effort, the Mio sometimes didn't notice (at times, showing a dropping HR when it should be increasing).
I had it tight (as they recommend) but it just wasn't as accurate as the Garmin - though the Mio Link data probably is fairly accurate for average HR for an entire ride as the signal was never dropped.
The newer Garmin Soft Strap worked well (no interference) so I think I'm going to continue with that. Hopefully it won't fail after a year or two as some on this thread have experienced.
I wanted to like the Mio Link, but I don't think the technology for wrist-based ANT+ monitors has evolved to it's fullest potential yet. The short battery life is also another reason to look elsewhere.
