Ok, what about using the popular L298N?  I was thinking along the lines of using 2 or 4 in some sort of parallel mode to get high currents.  Would that work?

I can't remember offhand if that chip can be paralleled (I think there was a recent post about it though, try a search),
but if so then you could up the current handling - but you'd not have the ability to use constant current drive from a
high-voltage supply (which is needed for high-speed operation).  If high-speed isn't a requirement it sounds a possible
approach (given my first comment).   [ just for completeness L6208's cannot be paralleled ]

There are higher current H-bridge modules available, such as the Pololu ones.

BTW do we know the winding resistance for the motor?
