I would strongly advise using the electronic muffs. We have several sets of the Peltor 6 that my sons use and I have a set of ProEars that I use with USPSA matches.
They work very well at allowing you to have a normal conversation, maintain situational awareness, and shutoff loud noises automatically. I agree that you will get what you pay for .. the more expensive sets, as mentioned earlier, do give you noticeably better performance.
