I have used a lot of different laminate trimmer / palm routers over the years, and my favorite is the older Porter Cable. I have one that I have abused for over fifteen years and it still works great. Newer ones seem to have the bottom bearing go out within a year. Now that DeWalt owns P-C, I don't know if I'd buy a new one.
>>edit: I like the fact that my template guide bushings fit the P-C laminate trimmer.
I have experienced the Colt router base's tendency to slip on the motor on more than occasion, with more than one router. I wouldn't take one at half price.
I have used the Ridgid and didn't care for the switch placement, but I was surprised by how well it worked and held up over time for how cheap it felt. Don't expect the plastic adjustment knob to stay attached to the bolt/nut for too long, though. The ones I worked with had to be tightened and loosened with a pair of pliers.
I haven't used the newer Makita models, but the old ones worked okay, they just seemed to be a lot more expensive than the P-C. Top-heavy.
I haven't spent much time with DeWalt's offerings, but the one I did use seemed top-heavy like the Makita, and generally not ergonomic.
I've thought about getting a new laminate trimmer / palm router, but I can't say I have seen any good options. The MFK looks great, but costs five times as much as most other small routers. It's an investment I'll have to wait to make, or try to find an old P-C somewhere.
