Replacement for MercuryMover
The site has a general options list as well for the window management category at: What Window Management Options exist for OS X?

For your specific requirements of keyboard, HUD and non-text preferences, I would select either divvy or moom. The former is one I've selected for several clients and they have enjoyed it and adopted it easily. Moom is also awesome and has some nice gestural / mouse / trackpad workflows.
