Best Wireless handheld mic

[mattsk42]

Must be ultra reliable, under 500 dollars, and would prefer Shure or another big name company in the same quality.

It is for a lead singer who's used to using SM58's and likes them.

I know of a few, but wanted to get your guys tried and true suggestions.

I've used this in the past with great results.

You just pop it on the end of your favorite mic and ...
voila it's now wireless.
You also need the reciever of course, but it's well under $500,
and it's UHF which is important I think. I used it with the SM58
you mentioned. I never tried it with any other mics.

I know this website says "sold out", but I'm sure you could
find more places that carry them.

Good luck.
