KT, the only covers I've seen are the Wolf/Bill ones that they made for me and a couple of the Kistner ones from Miggle. The ones I have are a thin vinyl and stick to the board by the adhesive that's on the back of them. These covers are the prototype material that Bill was trying out. The adhesive is a little too strong for constantly taking the cover off and on, but that's ok by me. Each of my Alternate League teams will be getting it's own board w/cover, so once I put the cover on, it's there to stay! I haven't had them long enough to rate their durability, but I would have to say that as long as you're carefull, they will last longer than you will.

As far as play goes, I've done a few games with the Sasquatch field and am quite pleased. The vibrations are smooth and consistant. Without the cover I had to turn the volumn down whenever I got close to the endzone where the motor is so that the players wouldn't fall over. With the cover, I can set the speed and leave it alone no matter where the game is taking place. I haven't had the chance to play any games with the other 2 covers, but don't expect them to perform any differently. I believe the Miggle ones are also adhesive, but not as strong and can be removed several times without affecting them. Again, from what I've been told the covers help smooth out the vibrations. I have no experience with any magnetic covers.

As far as cost goes, you'ld need to contact them. I believe the Miggle ones are $70 or thereabouts
