Replying to Beginner Park setup?

Guys, I need ur opinion. I want to make a budget Park setup for a beginner (me). I have the option to buy a secondhand ski and binding for about 300 bucks. I found a armada arv 84 2020 and a tw pro 2022. I will probably find more in the future. The other option is to get a new prodigy 1 or a revolt or something similar in a sale online for about 400 bucks. But then I need a way to get some cheap bindings. I don't want to spend too much money cause I don't spend a lot of days in the park. What do o you think?
