Yesterday I received a catalog from Marlin P Jones co they  sell surplus 
electronic components. They offer two thermo electric assemblies for 
around $30.00 .Might be what your looking for. They have a on line 
catalog at www.mpja.com
I have no affiliation with them,however I have purchased from them in 
the past and found them to be reputable merchants.
