Honestly Diki..I am not sure what to suggest by way of sims. I do agree with you about practicality of carting a Leslie around if its not your main instrument. Although for someone whose primary instrument is a Hammond or Hammond Clone, a Leslie (or similar) is pretty essential (unless you own a KeyB...but even then for appearance sake you might still use a Leslie.) But if you are using the organ patches on the G70, then the Ventilator will probably be fine for you.

I just find it dissapointing with the technolgy available to us today; you would think that at least one manufacturer would do a good job with a simulator.

In the meantime...i will keep listening to demo's and if one comes up that I like i'll post it.
