Most of them can be had for $20, but that is probably going to be changing VERY soon, since MR has announced that they will not be selling ANYTHING in 2008 even though they can until their sell off period is up..
I say go for it, because they are going to become a little harder to find. They are very nicely detailed pieces, and great for those that don't have a lot of room for the more expensive LE, CE, SE, EE hilts.
There are a few that are more expensive to aquire, and that are quite rare, but they are around the $100+ ballpark for some.
