I got everything I can reasonably need or want for a year and it ran $300.
Vaping = happiness whether you spend $200 or $2000, but that's not everything in life. take it easy. focus on friends, family and health (as you obviously do, not smoking); toys (yes, I said it, toys) wont bring you happiness in the long run. Its just stuff after some point.
There is no reasonable reason you should spend $500 on equipment.
