Below is a list of sellers (in alpha username order) that I've done business with on ebay.  I tried to provide as much information while keeping it  short and simple.  I hope that you may find this useful and can use it as a reference in your future transactions.  Maybe we should have an online searchable database on sellers where we can all contribute?  It is small, but it is "work-in-process", and a start.  I hope to expand and may even re-organize as time goes on.
