Replying to Cheap park setup?

Right now my quiver is a big all mountain ski in the jeffrey 108, and an atomic vantage 86 for on piste and my PSIA exams. I use the 108s in the park because I love the ski but I really want something specific for park jumps and rails. also skinner and a little shorter.

Problem is I'm poor as fuck and with coronavirus I haven't exactly been working a ton this year because I'm a bartender/server in a state that's still on lockdown...

I really want a dedicated park ski but don't have the money for a new setup and bindings, are old/used park skis a good idea or should I just save for next season and get a newer pair? (not prefered)
