ETA 2836 - Should I replace balance assembly or just buy a new movement?

[pr0digy30]

Back in the fall was working on my 1655 and messed up the balance assembly when it was upside down and pushed a little hard on it (should have been using the movement holder, but hindsight is 20/20).

I see Ofrei sells the complete assembly for $60... but I always had a problem getting the balance wheel to catch the pallet fork, even when I tinkered with 21J movements.

Now I see Helenarou sells a GMT 2836 for about $130. Should I attempt to repair the 2836 (assuming nothing else got bent up on it), or should I just pop for a Helenarou movement and use the 2836 for parts?
