Thanks folks.
I have stumbled across a few over the last year or so, but looking on eBay now - the only ones are M&N or college. There was a nice Titans one (think it may have been Kearse) that I had been watching, and could have got it for something like $60. I really regret passing that up now, having seen the quality of these. Would highly recommend them to all!
Incidentally, this is an "X-large", but equates to a Reebok 48. I know Ripon made these for the Bucs in their old creamsicle alt (the white body which had red numbers with the creamsicle trim.) If I am able to find one of those to add to the Sapp, I'll be very happy.
