I refinish wood floors. Besides sanders, what festool tool is a must

[Ta2ude]

PA I am a full time flooring guy. I install pre-finished hardwood and laminate, I do not do sanding and finishing. I use my TS55 and Citi Midi, with a Stanely adjustable speed square http://www.stanleytools.com/default.asp?CATEGORY=SQUARES&TYPE=PRODUCT&PARTNUMBER=46-053&SDesc=Premium+Adjustable+Quick+Square%26%23174%3B+Layout+Tool to cut the boards at the end of the row and it works great, especially when you are installing on the second floor,no more running up and down the stairs every 4 or 5 rows!!! I make my cuts on top of an empty cardboard box that the wood comes in right on top of the floor. I still have a table saw set up in the garage or porch or driveway, for cutting vents, around door jambs and ripping my last row etc. but  the TS55 and a rail works wonders for that last piece up against tile that is on a slight angle.Just measure, mark with your knife, set the rail on the marks and go. sometimes a light touch with a hand plane is needed to make a perfect fit but no more eyeballing a cut down the table saw.  It also works great for cuts that are over 45 degrees that you can't make with your chopsaw. I have an OF1400 that I use for installing medalions and making nosings sometimes which is also a very nice tool but it doesn't get used nearly as much as the TS55. My next purchase will be a sander I have been debating the RO150 for a while but it's very $$ and really won't get used that often so I am still struggling with the idea. My last truck payment is Dec 21'st though so.....
