So these stupid ads on DJ's site got me wondering. I clicked this one.
START PRINTPAGEMultimedia File Viewing and Clickable Links are available for Registered Members only!!  You need to or END PRINTPAGE
Then I thought well lets look at the FREE preview.
I read and thought well, I've had these for 32 years now and I found no information that dropped me off my chair.
  Then I thought, thirty years ago I would have given my left nut for that information. So I dont advocate often to buy anything you cant get for FREE, however I would recommend newbies check the link out. ;) and read the FREE preview. ;)
Information is better than money with CH.

I agree.  My only concern with them is sometimes newbies see those ads and think they are DJ's responsibility and or they buy what is being sold.  I try once in a while to post a note letting our newer folks know that all ads are just that, ADS that are placed there by Google, not DJ.  Anything read there does NOT have the impremateur of DJ or anyone on the site itself.  Buyer beware!  If you have a question ask and you will likely be told to "save your money".

JMHO
