For anyone around Anchorage, Alaska, I had a good experience with:
Alaska Hearing Aid Institute, 907-344-4900 or 888-554-4242 on the corner of Denali and Benson.
I don't live in Anchorage but travel through twice a month and dropped by while waiting for a flight delay. They were very good about taking me on short notice, I phoned from the airport and was in for impressions 20 minutes later. They evidently do a ton of impressions for oil field workers (like me) and make a lot of custom hearing protection. I'm not sure, but I may have gotten a bit of a price break by virtue of my employer doing lots of business with them. They charged me $50 for two separate sets of impressions, secured in shipping boxes and mail pouches. They followed the UE instructions I showed them on my laptop, although they seemed to be pretty informed on taking impressions. Both sets of impressions looked good and identical to my ignorant eyes and the technician who did them said "
they won't have a bit of problem with either one of those". Here's hoping...I sent my impressions to JHA for a set of JH13 and to Fisher Hearing for custom molds on a set of TF10's. It will be interesting to see if there is any difference between the fit outcome of the two shops.
They told me that it would be prudent to get the impressions to the respective labs rather rapidly. They said that impressions have a tendancy to shrink slightly after the first 10 days or so and that most fit problems they had seen they attributed to slight undersized molds from impressions older than 10 days. Don't know how accurate that info is, but I sent mine out priority mail the next morning.
Hoping for a couple of perfect fits on the first shot here

Both my JH13 and Fisher remold TF10 are here now. Both are a very nice fit.
Thumbs up for my impressions, and for the whole custom purchasing experience.
