I've wanted to try the Diva Cup or Keeper for years, but just kept putting it off, partly because of the initial investment (which isn't really that much!). FINALLY ordered one and used it for the first time yesterday.
Here's a link for newbies: http://www.divacup.com/
For heaven's sake, why did I not do this SOONER?!?! This thing is so easy, the instructions are comprehensive and everything I've heard people mention as concerns are totally addressed. If you really follow the directions, it's pretty foolproof. The learning curve is significantly shorter than I expected and I'm sold.
Last month, I was extremely frustrated on a road trip, not really being able to get to a bathroom as often as I needed and now that's not a problem anymore. To only have to deal with it once in the morning and then before bed is totally worth it. LOVE IT!
(Last time this was discussed on here, someone mentioned the suction being so strong it could damage -- you just have to break the suction! Like when you're nursing, you don't just pull the baby off the breast without breaking suction first, or it's gonna hurt! I read the instructions completely a few times before I needed to use it, so I was really prepared.)
