No,
After it's all said and done, the only thing worthwhile about the DX05 are the extras. The boots are pretty good as well as the accessories, except the whip, but the head and clothing need to be replaced.
You'd be paying $400 for the boots and the accessories. The pants are okay, but the shirt is bad. . . tailored oddly, it's got padding sewn into the shirt, so the already too big muscle body makes the whole figure even more oddly proportioned.
You'd probably end up paying $600-ish to go the custom route and end up with a much better figure. That's if you can score the Yunsil set near original cost.
With the DX05, you'd pay $400, and still have to pay another $300-$400 to replace the clothes and head.
