I'm working on a Pavehawk and for x-mas I'll get the DAP.
I suggest that you get at least Eduard's exterior set for the UH-60. It has many details (antennae, meshes, hyraulic hoses etc.) that will further enrich this model.
If you want to have a look at it, here's the link:

Cobra models has a weapons kit for the M-230 cannon wich looks very impressive; here's the link:
