Check out Matt Graybeal at Justcage. He advertises everywhere and his prices generally are less than the other sources. Also, he has occasional outstanding sale prices. I've seen the bottom line dbs 1000 Helix as low as $109.00 sometimes. As well, he has excellent prices on on/off thermostats, which is what I use, and is MORE than sufficient for corns. I bought a Johnson from him for only 72 bucks. I'm very satisfied with his customer service as well. Just my 2 cents.
