Scott,
if you can make a little effort, go for the Roland A 37: it has 76 waterfall keys (the optimum to play organ sounds), 128 memory locations, two midi outs and you could use it to play your Tyros as well, realizing everybody's dream: a 76 notes Tyros!
Last but not least: it does not cost a fortune.
