Suds, you did not mention your friend's experience level woodworking, especially with routers. This is a factor I discuss with everyone seeking my advice.
I bought my first electric router in 1946. At the time I bought my first Festools in 2006 I owned 8 routers of other brands, only one of which had a plunge base. As my first Festool router I selected the venerable OF1010, because I wanted that for drilling LR32 holes. Back then the OF1400 was not available and the OF2200 does not attach to the LR32 rail device.
Subsequently I have added many OF1010 to my tools, as well as 2 OF2200 and several MFK700. I only own one OF1400.
For me the OF1400 is Festools sincere effort to produce a very versatile router, which means there had to be design compromises. I am delighted to find that because the OF2200 is massive and runs so smoothly, for me it handles hand operated as easily as does an OF1010. For most of the tasks I perform using a hand-operated router the OF1010 has more than enough power.
Personally I make a whole lot of raised panel doors, for which I have been using router tables with conventional routers for decades. Consequently I own a comprehensive collection of 1/2" shank panel raising sets. Many of those go back to before the OF1400 was available in the USA. What I discovered after buying my OF1400 is that very few of my panel raising bits are small enough to fit on the OF1400. That router can be attached to the Festool LR32 "Holy Rail" device, but doing so is a PIA compared to using an OF1010.
Bottom line of my advice is to buy an OF1400 only if it will be your only router. I suggest the OF1010 as a first Festool router. BTW, my experience is that for most tasks the OF1010 collects dust and chips as well or better than does the OF1400. Perhaps this is because I have thousands of hours of experience with the OF1010 and probably less than 100 hours with the OF1400. Trust me, in the real world by following the advice contained in OF1010 supplemental manuals, you will be thrilled by the OF1010 dust collection.
