Dave and Dwight are right,get the real thing,an LA made box.
They are the instrument of choice for Cajun Music interpretation.
They are usually very well made, and if you go with one of the good builders you should not have any problems.
What I have said in the past and will say in the present about one aspect of their construction still stand, but that's me as I love venerable and traditional craftsmanship techniques applied to their constructions .
My theory is that as well, that a little extra money when needed, can be find, if necessary to spend on one self.
The key is to be patient.After all this is an interesting , life time hobby to be involved in , and I hope not to sound to patronizing.
