They look like nice average hi-yellow to me. This is the first morph I had and will always have room for a few, so my vote is yes if they a reasonably priced.
To me the top 2 look like high yellow on the right and hypo tang on the left. The bottom one could be normal or high yellow. I imagine it's either going into shed or a little stressed because of the color. There are real cautions in buying (or I guess I'm supposed to say "adopting") animals from craigslist because of the potential for really sick animals and the unknowns about the sellers, however, these geckos have reasonable sized tails and don't seem to be on sand. A lot of us want to do rescues and I feel that a "rescue" from craigslist is better than one from a petstore because of the concern that buying from petstores perpetuates their irresponsibility. You could say that buying from craigslist encourages people to dispose of their pets, but it's much more individual and people have more of a variety of reasons. I'd say go for it, but quarantine rigorously.
They look like a blod designer or bold jungle my jungles look like them, That would be my guess they are great though, Its all about preference alot of people like these strains and alot dont its your preference though, good luck.
I would be iffy with it, but at least try to get a feel for the person selling it.
My opinion is the top left is Hypo Tangerine, top right is High Yellow, and bottom is Normal. But that's just want I think.
I realllllly think top left is Hypo Tangerine, because all of them that I have seen look like that with the head spots and 2 splots of spots on their body.
I think the other two can get mixed up more but the bottom one looks more like my normal, and the top one has a brighter yellow.
