The primary difference between the two will be the size of the capsule (mic element) and the low frequency response. The size is negligible to the audience at 20-30', so this is fairly irrelevant; and the low frequency response is not much of an issue, either, as most of this range should be attenuated so you don't pick-up a lot of rumble and speech plosives. Probably the biggest difference would be the distortion, but even that would be negligible through most PA systems (however, you might notice it in a recording made directly off of the mixer).
Sensitivity, self-noise, and maximum level before overload are all pretty much the same.
I say: Go for it. $78 sounds like a good deal (this price was found numerous places on the web, so it is probably a manufacturer's minimum advertised price).
Since the price is easily repeated, buy one and see if it works for you. If it does, them buy more. Or better yet, see if they have one you can test drive.

Subject: Wireless Mics
I have a parent wanting to donate wireless Mics so he can hear his child when we do our musical! I got a quote from a local company and the hairline Mics they quoted are "mini Mics" from Shure, and are only $78. The headset Mics are much more expensive. I asked the guy giving the quote if those Mics would give good sound quality for a musical, and he said, "yes". I see someone else on this forum asking about Countryman B6 hairline Mics. I looked those up and they were about $250-$300. I don't want to judge solely based on price, but I know you do get what you pay for. I'm also wondering if this local company here in El Paso has enough expertise for this job. Does anyone have recommendations for companies in Texas?
