They do look similar... I can see why the shape of the Yaxell is somewhat suboptimal, the handle isn'tall that important as I likely will get it replaced at some point. I guess both the appearance of the blade and the fact that the Yaxell is made of Sg-2 was attractive to me. There is little info about that other knife so I probably wouldn't go for it.
Personally, with a budget like that, I would get in touch with Mike Davis. He's a forum member and the sujihiki that I have of his is absolutely amazing. I'm sure he'd be able to make you something within your budget that will blow any factory made knife out of the water. It's the blade on the bottom.
