Apparently many people looked at this post but only a few had any ideas to offer. I read through those responses and will specifically use the long hose idea and will add 220v outlets when I upgrade to the power pro. Meanwhile, I think I'm going to take a very conservative approach due to financial and space considerations.
I will sell the overhead router set-up. That eliminates one item taking up valuable floor space. Instead of getting the pro fence router table, I will make my own router table similar to the one in the following thread:

( I don't know how to provide a live link but if you click on the link while pressing CTRL key will take you there.) After the initial post, see page 3, post #29 for a 520 fit. I only have to purchase front and rear rails and a router plate. This seems to be the quickest and cheapest way to move forward at this time.
The upgrades to the power pro and M7 conversion will have to wait.
Writing this thread caused me to think through my options and your input plus browsing through old threads has been helpful. It's like having a buddy here to discuss my options. Thanks for the ability to utilize this forum.
