That Oasis II is very nice. For the tall cabinets.

I ended up just getting a Hyrda that has aux fans to circulate air all the time too. It is like the Oasis XL just a little nicer with better controls. That one works fine for my cabinet(and would be plenty for the Lexington).

As Shelby said once you started getting boxes in there and everything within gets stabilized it is much easier to maintain the RH.
