You are probably mentioning some of my reviews... overall after years now the 3925 has served me well. However it all depends on what you want to make. From reading your other posts I don't think you will have a problem.
Sure my X is very gritty, its not "perfectly perfect" but honestly I love it. I did think about going bigger at one point
I would get the "bigger" router you can afford, try and get the 3925 at least...you can mount a solid MDF 2 feet by 4 feet slab on it...the others I think you will run out of room on. While they might have 14"X14" you won't be able to use all of it because of mouting, routher bit, etc.
Get a router with linear bearings, I think K2 stopped the roller blade bearing design which if they did is good.
Get servos with geckodrives if you have the option.
I have a lot of info on my site www.cuttingedgecnc.com
MOSTLY, by the bigger-biggest router table you can afford as servos/geckodrives/software/router, etc, will all pretty much cost you the same.
