At what point does a buffered KG become useful?

I traded a fresh KG a while back.. and I don't really need it. I'm trying to buffer it with my box so I can trade it for something..

Would you trade anything for 5GB buffered KG? (looking for =<3.5 trackers)
10GB?
50GB?
100GB?

When does it become useful? Is it even useful enough? (the site)

I think it depends on the guy you are offering KG to.

I would definitely give something good for a crazy buffered karagarga (50GB starts to sound interesting)

i traded a czone acc for a 170GB buffered KG
if i had a level 4.5 i would've traded with that as well
for me KG is one of my favorite trackers, what am i gonna do with another scene tracker even if it was level 5

i give 275 gb swebits for 150-200 gb buffered KG

it is difficult too seed at KG so if someone is looking for it I magine the get interested at 25+ buffers
