For possibly the best Hammond sim in an arranger, I can't recommend the BK-9 too highly. Seems a shame to blow a large wad of cash on a one trick pony (unless you HAVE a large wad of cash!). The BK-9's Hammond sim compares quite nicely with Nord's (which I've played) and most other sims. But throws in a great arranger for little more (or even less) than most dedicated clones.
