I'm thinking of getting an Innerspring Waterbed Replacement - what is your experience with them?

Do they suck, or are they worth the money. I really don't want to spend a bunch, but I can't imagine that it's as good as a traditional box spring and mattress setup... Thoughts? Experience?

I switched and it was the best thing to do. I would recommend the same. I had no problems with mine, and i felt better.
