Welcome to the forum, I had my own ordeal with cancer (kidney) they took half of my right one, so I know how you feel. Can't go wrong with an eGo I still have my 1st 510 stick style and it still works! I'll be closing in on 2 years analog free in a hand full of months and I know if I can do it anyone can. Stay focused and don't beat yourself up if you slip! Good Luck
