May someone give me the details of the vending machine, and or your opinions of which one you like most?

This link may be of interest to you?

I usually vend most at frosty claw and blue sky.

Yes that is helpful, I did not know subeta lodge had a guide page. haha

I usually vend at Ocean Depths, but you might not have that if you didn't complete the map to get to the Omen Islands...

I like Prize Get. Weapons sell pretty well because of Maleria asking for them exclusively
