Yeah, the ecosystem module rocks totally, and I am just learning to use Vue. But it is very simple, and very much worth the $99 add-in prices. The only difference between V6Pro and V6E is that Pro includes all the modules and a unified serial #, where in V6E, you can buy the modules you want one at a time (but do have to manage different serial #s). It costs more to do this if you are going to buy all the modules, but if you are on a tight budget (like me) and want to get going, V6E, and adding in what you need later, is a good way to get there. Pity the Ecosystem is the most expensive module, but as I said - well worth it. Sorry for the ramble - not feeling well, and brain is mush.
