Matt, several of the cabinet shops, and solid-surface shops that I sell to locally use the Festool air products. The solid surface guys specifically will never go back to the dynabrade or the hutchins..to name a couple. They are indeed a bit more dough, but worth every penny.
One thing that needs to be addressed with SS is the "shop vs. field" application. If a person is going to sand in the shop with their LEX sanders, then they had better utilize the LEX in the field as well. The throw patterns are different enough between the Rotex and the LEX that a person WILL see a difference in the finished product. Long story short...If you don't have air in the field at the install, use the electric sanders in the shop.
I have one guy in town that just bought 3 packages from me. Most are going with the 150/7 and the 150/3 kit with the Vac. And I quote, "S$@# if I am going to spend that much, why not go all the way and do it right." The single most important factors was the dust extraction. SS is a messy thing. When I demo the tools, THEY ARE ABSOLUTELY AMAZED WITH THE LACK OF DUST IN THE AIR.
Theses are the Guide Lines I use for Finishing SS with regards to Paper and sequence:

Same sequence as listed for gloss; but you are now going to throw down some compound and buff the sucker!
USE THE ROTEX:
Hard Felt - Marine grade Rubbing compound
Soft Felt - Finess it II (my preference)
Wool Pad - Liquid glass
When I'm polishing I use the same methods as with sanding. You need to make sure that all the compounds are cleaned up before moving to the next.
