I'm a member of the club and I think it's awesome. The membership kit right now includes the Steppin' Out Beaker and Bunsen twopack and a few other little things.
Being a member of the club you are able to purchase every convention exclusive they make. Take the Culinary Catastrophe Swedish Chef, for instance. He was only available at the San Diego Comic Convention, but I was able to buy him for the regular price ($20 I think) + shipping. They also offer chances to buy special industry giveaways, like the Black Jacket Rizzo.
This year, we even got our first club members only exclusive, holiday Rizzo. He comes with a red Palisades T-Shirt and white jacket w/ green sleeves that says Happy Holidays on the back. He also has a cloth Santa hat. For every Rizzo purchased, Palisades donated a toy to a charity toy drive.
I'm proud to be a member of the club. It's definitely worth the money. If you collect Muppet toys, I'd say you would definitely get your money's worth out of the club.
