Just wanted to let any members in the Denver/CO Springs area know, that a gentleman by the name of Glenn is doing the silicone type molded ear plugs for $25/pair+tax (~1.83). I got one pair and they work great, and I'm going back today to get a second pair, for a spare. Here is the link to his craigslist ad: I Will MAKE CUSTOM EARPLUGS His phone # and web site are listed in the ad.
You can make these on your own very easily - try Amazon.com: Radians CEP001-R Custom Molded Earplugs, Red: Home Improvement
