What kind of wireless microphone is best for me?

[The big L]

I'm a drummer in a band. Unfortunately, I am the lead singer as well. It becomes a challenge trying to get a good sound without feedback. The wireless mic I've been using is a basic headset(falls off alot) and Audio Technica DR15 transmitter with DR10 receiver from DR1000 series.
I have been looking for something:
that will pick up less background noise (mainly drums)
is less likely to increase feedback (if that is even possible)
that picks up my voice well (I'm not the loudest singer)
and will actually stay on my head while rocking out on my kit.

I've found 2 so far that interest me http://www.musiciansfriend.com/product/Sennheiser-EW152G2-ME3-Headset-Microphone-Wireless-System?sku=276676
and
http://www.musiciansfriend.com/product/Crown-CM311AESH-Headset-Wired-for-Shure-?sku=278414
So, which mic would you recommend from above? (or other)
What kind of receiver should I buy to compliment the second mic? (if that is the best choice)
Also, my price range is about $700 max.
Thanks

Go with the Sennheiser ew152G2 ME3 Headset we have these at work, i work an audio/video rental company and this is an incerdable mic system well worth the money

My primary experience is in theatre audio, but I do occasionally work with musicians. I have encountered the singing drummer issue a few times before and unfortunately the best solution is to get either a new drummer or a new singer. If that isn't an option, as it probably isn't, you need to look into something that doesn't have a very big pickup pattern. I swear by sure microphones, and my personal choice would be this:
