I have the X6100 and it's actually a very good radio. If I had a complaint about it, it would be that the receiver can become overloaded with strong signals. I used it at the Titan Missile Museum's HF discone antenna last year and although I was able to make contacts on 40 meters all around the south western United States, I ended up with a lot of adjacent channel interference from an AM radio station a few miles away. I've also used it in many remote mountain locations and on the Channel Islands off the Southern California coast. In those situations it worked extremely well. When I use it in an urban environment it just gets a bit noisey. Beyond that the radio has an excellent built in tuner. I usually use it with either a dipole or an EFHW, but I'm also used it with a random wire and a counterpoise wire on a BNC binding post and it works. The tuner will tune just about anything. For the money, I'd say it's really pretty good.
