The Lee Bench Plate system started me thinking along these lines, but I am not sold on their product because I am concerned about a wooden base blank cracking (I have cracked a workbench top before). Actually, I should say that I am not even considering the Lee, but I am looking for alternatives.

Then I stumbled across the Pat Marlin ROCKDock system.


It seems far more solid, will also work with non-Lee products, and is only about $20 more than the Lee.
Anyone have real-world experience with a docking-style press mount system have recommendations regarding these two -- or any similar -- products?
