...But if I take one of those tracks and align any piece of it to a grid, it gets all out of sorts. Basically, at least for us, you have to either leave it alone or align it all to the grid. Anything in between just plain doesn't work.

Personally, in those cases I prefer to align the grid to the recorded audio instead, making new parts easier to match up while still leaving the "feel" of the original.   That's one thing that Melodyne 4 does very well - tempo mapping. 

An update to this. I did purchase Melo Editor for the lower price and was successful at upgrading it to studio. So total cost for studio wound up being $498, $349 for editor and $149 for the upgrade to studio.
 
So if anyone else is interested in saving a bit to get from Essential to Studio, I would recommend this path.
