Hi!
I would only recommend a GD if you are willing to endure the learning curve of how to hone and maintain it. I ordered 4 GD 66ers for my first razors. I knew from the forums what to expect. It was more of a challenge/a project for me than a necessity of having a good razor to start with.
Here are three of the four. I dumped the fourth one rather quick because I just couldn't get the heel half (!) of the blade to cut hair. They are a pretty crooked bunch:

The first one looks worst - is far far off center. The other two are "OK" - the middle one being my best. As long as they lie completly on the hone you'll be alright. They all do, although two have a wavy grind, so that some sections of the bevel stay matt while polishing. Remarkably, one side of the "wave" does lie on the hone, so that the edge still sharpens.
To make my project even harder, I honed solely on a Belgian Blue Whetstone at first. Setting the bevel on the hard steel didn't work right though, so I set it on a 600 grid Diamond Sharpener, which flattend the "waves" a bit too, then went to the BBW and did something similar to the Dilucot Method. After that, I stroped them on Cromiumoxyde and leather. I took serveral attemps, changing and improving the steps along the way. I figure I should get a 1000 grid stone for bevel setting. For maintenance my BBW and strop is sufficient.
As a conclusion I can say that it is possible to get the GDs shaveready with honing alone, but you must reckon with several razors before you find one really useful one. Two of my four have turned out to be decent shavers. If you can regrind them much more is possible. I fancy thinking that in China men are using the same primitive and badly made razors and have nothing else. I'm sure they get good shaves out of theirs as well.
Happy Honing,
