Recommended Repro Reel Cassettes?

I see a lot of you have really nice looking repro reel cassettes in your boxes. Could anyone recommend a source? There are several sellers on eBay with them and the prices are all over the place. I'd like to get them as cheap as possible since they'll be mainly for display and making a few simple demonstration tapes. I searched around here and many of the old sellers are no longer making them.

Best bet is the soviet sellers, like these:
