Well, none of them are going to be special, get the most powerful one you can, or you will stop the belt with not much pressure.
I still use an axminster belt grinder for a lot of my work, its got an 800w induction motor and i can still stop that. Cost about £250, and its my most used grinder, great for bevels and handle shaping. personally i'd save to double your budget, and get 20x the machine. Its not 1" belt, but i've used one to make nearly all my knives since 2009
This one here, though it looks like thay have pimped it a bit since i bought mine.
