Amazon.com has some reviews from buyers that might be useful. I'm going to see if JET has one available at their local warehouse today which is why I've found this info. Here's a brief summary of the Amazon.com comments:
JET CD-1200CK: 3 reviews. 2 gave it 5 stars (the highest rating possible),
1 gave it 4 stars because the switch is a foot off the ground. If you use a remote switch this would have no negative affect on you. One person mentioned a small air leak that was easy to fix. Here is the URL if you want to read the reviews:

CD-1100CK: 15 reviews. All 15 gave it 5 stars. The only complaint was from a couple of people that mentioned a small air leak that was easy to fix. I believe the 1200CK and 1100CK are identical except for the HP so I would expect these 15 reviews of the 1100CK to be as useful as the 3 specific to the 1200CK.
