Personally, Honeywell's are my choice.
Be sitting when you look for the price!
Thanks Freddy. I looked at a few of them before and yes I was a little shocked at what they want for them. I also bought some brass fittings a couple of days ago and was a little shocked when I paid for them. I'll go with the Honeywell based on your opinion. I do have one more question regarding mixing valves. What happens when they fail?? Will they allow too hot of water to go past them? or will they only allow cold? The reason I ask is that I don't want to ruin my tankless if the mixing valve would happen to fail. I've had new things fail right out of the box so I've learned that a guy can't be too careful.
