WTB Braves hot dog SGAs 1989, 1997, 1998 -- does anyone have suggestions for a source

[Mungo Hungo]

For about 15 years from the late 80s to the early 2000s, the Braves' hot dog vendors sponsored SGA sets that today are generally hard to find.

I'm looking for five:

1989 Dubuque Braves - Jeff Wetherby
1997 Bryan Braves (non-perforated) - Chris Brock
1997 Bryan Braves (non-perforated) - Mike Cather
1997 Bryan Braves (non-perforated) - Chad Fox
1998 Bryan Braves (non-perforated) - Kerry Ligtenberg

Few people care about these issues--aside from the HOFers who appeared in those sets--so the commons tend to get stuck in drawers and never see the light of day. It's not hard to to find Glavine or Smoltz, but sure seems tough to find Jeff Wetherby. Anyone able to help--even with just a referral to a dealer/collector?

Thanks-
Jeff
