I just searched on Ebay for a taishogoto, out of curiosity. They don't have any for sale at present, but my search did bring up two entries for materials (one video and one DVD) on learning to play the taishogoto. Both of these entries use the alternate spelling "taisho-koto" or "taisho koto".

So I did a search on "taisho koto" and found one listing of an instrument for sale. For thiruvasakan's and Foolestroupe's information, the seller wants the bidding to start at $99.99 US dollars.

Looks kind of interesting, but I'd still rather get a Marxophone...
