There is only one wallet that has self-custodial lightning addresses (to receive zaps), and that is @ZEUS in their beta release:

With all due respect, maybe do some research before throwing money at something. @OpenSecret  doesn’t have lightning address receive support (yet, I’m sure they will at some point). Any self-custodial wallet will have channel open fees. Some less than others. 

I encourage you to listen to @ODELL talk with Evan, the creator and maintainer of Zeus wallet in his latest Citadel Dispatch episode:

 I'll take a look, thanks!
