So..do you have any left at $58 for me to try? - I'd give it a go at that price. I'm looking at yours or an Auber instruments set up. I think a 10cfm fan would work.
How does your controller work in cold weather? Any problem in colder temperatures? This appears to be bit of an issue for other systems.
I certainly do not mind reviewing the product. Let me know if there are any left at the promotional price.
