Hey, I'm looking to get a telescope. I'm a student so my budget is pretty limited, 150 euros max. I looked for something used and I've found a few options but I don't know which is better. I'm mainly interested in lunar and planetary viewing, nebulae would be nice but not the priority. First there's one that's 150/1400

there's another one that's 114/900

and the third one is 150/750

I'm not familiar with any of those brands so I don't know if there's something I should watch out for or anything. Appreciate all advice, thank you.
