Hmm…Both seem like equally good options! I think it honestly just comes down to how much effort you want to put in. It seems like both options do not come with a set of strings, so you’ll need to invest in those. Both options seem to have tears in the skin as well, so that’ll need to be factored into cost as well.
However, there’s one thing that you need to keep in mind: the first link you posted is to a nagauta shamisen. The second one is a tsugaru! It all depends on what you want.
I would weigh out the pros and cons of each listing. The first one doesn’t seem to have a case, while the second does. They both seem to come with a doukake, and they both look like quality instruments.
My final thoughts? Both look amazing. It depends on the size of the dou that you want. You want a nagauta? Go with the first. Want a tsugaru? The second one, then. In my opinion, my choice would be the second link. I’m a bit biased though. I have two nagautas, but not a tsugaru. It also seems like a better value. And from what I can derive from the pictures, $250 USD is a paltry amount for what is actually in the package. It seems like a real deal!
Anyway, have fun choosing. No matter which you pick, it’ll be an amazing choice.
