After hearing about mixed results and turnaround times with the guy at TK from my classmates a few months ago, I looked online and found good reviews for the ear molds at pilotstuff.com/AverySound. I paid $67 for what they call the satin soft mold with color and $14 for the bar it snaps onto. Shipping is free/included. You can order additional molds at a discount, but I didn't do that. A few days later a little ear mold kit with good, detailed directions arrived. My wife helped me make the impression, I shipped it back using the included materials (postage prepaid), and I had a very comfortable, very satisfactory custom mold in hand about 2 weeks later. Highly recommended.
