Aside from issues mentioned in above article:
Numerous exhibits cards of Ruth can be found under 1k, depending on condition. Also plenty of strips (w516, W514, w520 and w519 being my favorites of the colorized strip types) Plenty of other black and white ones too like the W502, which has a nice portrait.

For under 1k (depending on grade) you can also sometimes get an R315, either W517, Shonen PC, maybe a low grade Sport Kings. E121-120 issues are great but would have to be really hammered to be under 1k.
