Laura,
We have the Eric Tindell boxes now. We just moved to them a couple weeks ago. Most of the dogs adjusted fine but a couple are bobbling more than usual. I really like how light weight they are compared to the Glover, Freda (Willoughby) and Premier boxes.
I have owned a glover box and sold it. I still own a Freda box and I purchased the Tindell box a couple weeks ago. FBI owns 2 premiere boxes but we have had problems with them so never use them.
Tindell is not taking orders right now.
I tried out the Jim Sova box while playing U-Fli in Memphis. Riot did fine on it without having issues. You could check that box out too.

Next time we see you, feel free to test the Tindell box or if you are up my way, you can test our Freda box out.
