I do think the tool is cool but I too wonder how much I'd use it, b/c I know at times I like to grab and stamp....so I have to think about when does a tool b/c too cumbersome that I don't use it....But I like that you can restamp in the same place again if needed!
As for the price----I found out a few years ago, when I wanted to have all my clings, and clear stamps mounted on plastic for storage that plastic/acrylic/acetate is expensive just on it's own if you buy at Home Depot/Lowe's!! and at that time (2 yrs ago) someone told me then, that plastics' prices had jumped alot--and I think they went on to blame oil and gas prices...etc..etc.... So it doesn't surprise me too much that it's that high--it is alot of acrylic in the product, then you add the rulers (which would be totally cool if they were accurate--and the more accurate things are the higher they cost), and the shims/one magnet then it all starts to add up.
