Well, I have resolved to actually get the instrument, even though the replies to this post have not been exactly recommending that. I am not expecting much of it, but I can't really afford much more at the moment and I just crave playing it. I know it may not be the best, but I certainly won't give up and I will eventually get a better one when I am more financially able. I am no stranger to broken instruments (my first guitar had only three strings and my first accordion practically had a drone note) and so I pretty much constantly prepare for the worst with this kind of stuff. That being said, I found two videos of this concertina being played, and I actually don't think it seems too bad just to start with.

Either way, I will be getting it. I know it would be ideal to get something better, but at this point in time and for a while I will not have that option. If it is bad, I will not give up. I have spent the past year or two wanting to play the concertina because I love the music it can make. One specific concertina being bad to play would not shake me off of it for sure. Anyway, thank you for the responses.
