Hello all, looking at two electric smokers. MES 40 and Bradley. I had a MES 30 and always had trouble keeping smoke. In fact quit using the tray all together after getting the AMNPS. The idea of the generator is nice but can you control the amount of smoke it puts out? I've heard of Gen 1 & 2 MES40, how do you distinguish which you get? Been through 2 control units on my MES 30. I do a lot of cold smoking. With the Bradley can you use the generator without putting heat into the unit? Obviously with the either unit I could just use the AMNPS. Thanks in advance for any info.
