What do you guys think? (suggestions)

So I had my Nagauta Shamisen for almost 2 weeks. (its a basic set-up) the Sao (the neck) is one pieces.

So I’m thinking about selling my first Shamisen set (price range - $200.00 with shipping) to upgrade to a Chuzao Shamisen (the seller) - is giving me a complete set. (comes with a hard case and (upgraded) bamboo ivory “koma”

I don’t know the price for the new setup (not yet. . . still discussing prices)

If your interested in buying my Nagauta Shamisen - here’s the previous link (where I bought it) - http://www.ebay.com/itm/150732295287?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
