First of all, hello to Everyone at ECF
thank you for any help and allowing me to join 
Now to my questions/help.. I have been vaping about 6 months or so and I love it. I have the DSE-901 and I love the vapor production. Recently I have been having problems finding a decent supplier because everyone seems to be switching to the DSE-510...
So what I am wondering is this.. Should I switch to the 510 as well? Can I use the 901 batteries / charger that I already own or do I have to buy everything again... ?
Also i am SUPPPPPER broke.. I have ejuice from Tasty Vapors and I am very happy with them.. I also need a USB pass through for the 510 or 901 no matter what I do because my usb passthrough broke again (2nd time).. Anyone know a super cheap source? I use to order from healthcabin but they are charging ridiculous prices for their shipping.. 18$ on 24$ order.. Help?
