one last thing you can consider is a CCK cleaver or go to any china town that sells chinese vegetable cleavers. there are ones that are short enough to work well in small spaces. try one out. they're cheap and i doubt you'll hate using it. everyone says those things are prep machines! easy to sharpen and very thin behind the edge. (not a cleaver for hacking through stuff, a cleaver for veg and prepping mostly)
i recommend the cck 1303.
