I went through V2 and bought a starter kit for myself with additional (5pack) of carts; came to about $88. Then I bought a couples kit and a 20-pack additional carts for my parents (heavy smokers), which cost about $120. Let me not forget liquid from primevaping at $30, and another $80 for blank carts from bloog. So I have past the $300 mark.. lol
I too started out with V2, alas before I found this forum. I got a 20% discount on a starter kit. Got the "travelers kit" which had a PCC, a manual KR808 passthru, and the car adapter (charging batts only, won't run the passthru). The package deal had 15 cartos included, along with a pair of batts. Paid $125.00 (incl shipping). That was on 1/31/2011.
Since then I've picked up another 20 carts from them for $1.00 (got credits for other family members getting a kit), so I can't really complain too much. Got some clearance juice from vaporcountry.com, 10mL for $1.49, bought 15 bottles worth, even if it sucks it was less than $25 with shipping (en route).
Another $7.00 at hobby lobby for some Lorann English Toffee and Cherry flavor, along with 60mL of VG, to try my hand at some cheap DIY with zero nic with the dead cartos I'm starting to accumulate.
I've got to say switching off nic carts with zero while I'm at my desk working is a GODSEND! Keep the nic carts for when I have a "smoke break", take 5-6 good hits and I'm set for 30-60mins. The zero I vape the rest of the time.
I'd love to try some dripping, once I get an adapter for a 510 atty for this KR808. The mods are calling to me as well.
