Yes, I've got a 5200G-R4, although I'm not using it at the moment. It's a perfectly decent router, and has some interesting geeky features for the adventurous, but you don't need to be a geek to use it. With the standard firmware at the time I bought mine, it had the strange characteristic that it overrode the target noise margin set in the exchange, and forced it to 6 dB. This was useful to me at the time, when my target noise margin had gone up to 15 dB as a result of a temporary problem. Later firmware removed this feature, and I expect current production models will have the newer firmware, but it can be flashed back to the older firmware.
