It's good. But all Scrapper combinations are good. It depends on what you're looking for.

I am not a big fan of DA so I would suggest a DM/WP. The one i have is a beast.
I'm trying out a DM/EA at the moment. Only have him up to lvl 7 but so far, he's pretty fun. Not sure how he'll pan out, but I'll play him in between all my other alts.

DM/DA is great scrapper at high lvls, needs a bit of working through sets to fully enjoy him.
DM/WP is really a beast but it's a boring scrapper, deleted mine at lvl 41 out of pure boredom and rolled DM/Invuln instead.
DM/Elec is really fun scrapper, specially at high lvls with Pyre Mastery.
DM/SR is probably the perfect boss killer and the cheapest one to build. He'll suffer from lack of AoE def between lvls 30-35 when you get Evasion but besides that gap, it's great fun scrapper to lvl.-
Tbh, Dark Melee makes any scrapper fun to play 
trying to find a good scrapper build is dm/da any good for a scrapper ?
