Great for real Hammond keybed and drawbars, and they sound fantastic hooked up to a Leslie 2102, but they're hopelessly outclassed in the arranger department. Expensive too.
I played an XE-200 for a few years, lovely organ, but if it's an all-singing, all-dancing arranger instrument you want, look elsewhere. For example, the drawbars on the Roland E-80 are as good, if not betterm and you get all the bells-and-whistles too.
The XE concept won few friends and is getting very long in the tooth now. I heard Hammond Suzuki had discontinued them?
