Help Me Choose Some eBay Carbs?

I'm mulling over 3-4 different sets of carbs on eBay. Anyone else want to pipe in on which set they would buy knowing all of them, at least, need to be rebuilt?

Ebay links:

1 shorturl.at/MtcKJ

2 shorturl.at/iIxoB

3 shorturl.at/lbaie

4. shorturl.at/QRzEG

I used the search term "1985 600 Ninja" ...

TIA

 

If they all theoretically need to be rebuilt anyways, since i am very frugal, I would buy the cheapest ones that are complete.  The way I value thing like that are COMPLETE>DAMAGED>INCOMPLETE. It can be hard to find individual parts for these old carbs. None of them look like they are corroded, which is something to look for. I would personally get 1. Or 2.
