Don't need an impact, just clean up the corners and put a metric socket on there, should be enough material left to get them out. If you are on a buying spree for tools, look at the battery powered stuff from Bauer, Rigid, or Ryobi, maybe Hart from Walmart. The previous three have been around for a while and will probably be around for many more. Get brushless motors whenever possible.
If you are on a buying spree for tools, I'd suggest one of the "big" mechanic's sets like one of the 300 piece set or 200 piece sets. All the way down to Pittsburgh (Pro) or up to whatever you can afford. Something like the Husky or Pittsburgh that you can walk into a store to exchange a damaged tool can be useful, but I've broken few tools in all my years and most of my stuff is cheap. If you need a pipe on the end of a tool, you probably should get a larger wrench, but I also cheat with extenders too.
