I regularly check Ebay for tenor guitars, there are plenty that come up for sale but they are getting more expensive each month!
I guess people buy them to keep so I assume they are becoming more popular & due to the demand prices are on the up!
Certainly compared to the prices I see on American Ebay, UK prices seem about double!
Here is an example of one that has appeared today... http://www.ebay.co.uk/itm/Harmony-TG...:SS:SS:GB:3160 that is about $630.
