I was able to see the SMS-1 in action for the first time at JimP's home... just a few weeks ago. I was impressed with the unit. Would I spend the extra money to own one? No. I can accomplish the end result with the BFD for much less money... I'll just have to do a little more work in making it happen.

The one fairly nice benefit to me that the SMS has over the BFD is the convenience factor. With the SMS you can easily pull up the on screen menu, hook your mic into the unit and run test tones over and over.... make adjustments with a remote... measure again and see it right on screen.

The biggest benefit the BFD has over the SMS is cost. The downside is you have to be willing to hook up your computer to it in order to see the measurements as conveniently as you would the SMS. Once you get it hooked up, it pretty much the same then if you are using REW.

The only other significant factors to me would be number of filters and amount of cut/boost these filters allow, along with two channels and more presets... all favoring the BFD. These may or may not be needed, depending on what your initial results are and how many subs you have. One other favor I see for the SMS would be cosmetic design... it's more appealing to me, but regardless of which one I owned, they would be hidden.

Another benefit for BFD owners who might need it is the BFD forum with some awesome specialized moderators to help out when needed with very quick response.

There are probably some other things I'm not remembering right now.
