I recently purchased a Trotec Speedy 300 and wanted to see what exhaust fans people have been happy with. I've read through the older threads and it looks like a lot of members are using the Grizzly and Harbor Freight. I'd like to keep this on topic if possible and also a true comparison for other members that are looking for this info in the future. Please state the following: 1. Brand/Model, 2. Price, 3. Distance that you are running the fan, 4. CFM, 5. Best describe the noise level, 7. Comments
