Advice needed please!!!

Have been vaping for years now and for last 18months been using a vaperesso luxe pod system, I'm pretty sure the battery is on its way out now as it just isn't hitting like it used to.

Since being on this pod system I've only vaped nic salts as I found 50/50 juice just dint hold flavour in the pods but this has become so expensive buying the nic salts constantly.

Is there anyone here that may be able to offer some advice where to go from here? I'm happy to get a new mod and so on but just don't know what's out there any more as not had to look for nearly 2 years.
