I still use that exact setup as a beater set when I'm working outside or something like that, it sits in my mod stand right next to the mechs and RBAs. Fantastic for a cheap set and gets the job done.
If you like the vape, I would suggest looking at the new iTaste VV, MVP 20 or 30, or the eLeaf iStick. They're all great simple devices, similar to what you have but with more power on the top end if you want to experiment later.
