[member=79486]Fourmi[/member] your story is very similar to mine, as far as multiple routers, set for specific tasks.
The main difference is that I don't have an OF2200. I have yet to come across the project where I would absolutely need one. For me, once I go that big, it becomes a router table operation. For that, I highly recommend the Triton (TRA001) The ergonomics are perfect for table use.
I would entertain the idea of Mafell, but their presence in the US is not so great.
Finally, the OF1400, far from my least favorite router. It is my top pick for 1/2" shank bits, outside of the table. It is the one I have sitting with no bit installed, so it can be ready for anything where I don't have a pre-determined set-up. The only issue I have with the OF1400 is with bushings. The only ones available from Festool are metric, which means calculating off-set is a problem, until metric sized bits become more commonly available. There is an adapter to use Porter-Cable bushings, which is a marginal help, at best. For shallow cuts, everything is fine. Deeper cuts expose a problem though. The collet nut is essentially the same diameter as the inside of the bushings. If you plunge into it, the bushing will spin right off.
For me, the least used and completely disliked, is Porter-Cable 690. It is just clumsy and top-heavy, in comparison to so many other offerings.
Battery powered 1/2" router = Milwaukee. The kid who works with me, as an apprentice, bought one a couple of months ago. He is already deep into that platform, so it made sense. I tried it a few times, with good results. It is a bit less stable than the corded model that it is copied from, because of the battery. It is more top-heavy on edges, but when still workable. I didn't try any big bits, but it worked fine with a 3/4" diameter flush-trim.
I have no interest in another battery platform, so it's a pass. If Makita did something similar, it wouldn't take an arm twisting [blink]
