Tom, I had a show last January  and will have one next month.  I bought frames through Dick Blick.  They were  Nielsen  Bainbridge Archival Gallery Frames.  They come with a 100% archival rag , museum guality mat.  They are kind of spendy but give you a great gallery look.  I sold  one of my photographs so that paid for two of my frames.  I hope this helps you and good luck.
