Give Stihl or Shindy a try, none are 100% perfect but you'll like both with dealer support. Lots of brands out there, you'll find people on lawnsite rawing or bitching for all of them, so it's a pick.
Only older style strato engines used reed valves, most don't but they're hardly a problem. Redmax made great equipment but not out-standing (i.e. stihl FS 250), they slipped with the whole emission thing and after the Husqvarna takeover rolled further down hill.
