Well in that case i kinda know what i'm on about
At work there are various folders in diffrent departments, ranging from a rather tasty 3metre hydraulic jobbie that can manage 10mm plate (probably bigger too but 10mm is the thickest we have), to rather small 1 meter manual machines that can do 2-3mm steel max or upto around 5mm ali - I have tired to bend thicker stuff with these but due to not being able lower the folding edge enough it just tends to shear it
Gone slightly OT their, if you want recommendations of which manufacturers are best IMHO then i'll have a look at work on monday (cant remember of the top of my head)

Still slightly OT
If you want to lower the folding edge, can't you add another slice of sheet below the one you want to bend as a packing peice?
This would raise the folded sheet with the same effect. You could alter the thickness of the packing to suit the difference in hieght required.
The main problem that I have seen with manual folders is that the clamping fingers are not strong enough for thicker sheet.
