1k list - is the Repulsor useful here?

Im just building a list with what I have, it’s not optimized or anything. Basically for leaning the game.

But the Repulsor is giving me second thoughts, should I really invest the time to build and paint it for 1k? I don’t even have that many units to transport 😂
