I have a large collection of stamps, most of them wood mounted. Some of my larger stamps just wouldn't give me a perfect impression. I bought a Speedball Press, made to use with lino blocks. Every stamp in my collection, clear and rubber, mounted and unmounted, gives me a perfect impression now. You can see my stamping results on my blog. The Speedball Press has made every stamp in my collection usable again:

I am not associated with Speedball in anyway, but I am very grateful for this tool
