Wow thanks guys was thinking many of them would be reasonable. Like $10.00 reasonable. I guess nobody makes the, these days? Those are mostly antiques.
I found a few listed as "new" that were less than $10 and no shipping. For instance:

That one is kind of nice too.
Edit for Additional info
A quick google search turned up an inexpensive repro of an old "marbles" style. I like this too:
