Hey there
I have MVP2 triplets and VV3 triplets. I am also looking at something a little different - I *LOVE LOVE LOVE* my MVPs, but I'm wondering what all the buzz is about with the Vamos or the Zmaxes, and even the Provaris. If I get something with more power, I'm going to try for something like 30-50W on the device.
I just picked up my 3rd MVP and VV3 from strictlyecig.com. Less than $70, including shipping, and it was to my door in just under 3 days. I also like 101vape - their prices are just slightly higher, but their base-color MVPs are 39.99. Energy and Shine are higher. Strictlyecig, base-color and Energy series are $37.99, and the Shine is only $42-ish. However their stock is quite limited at this time. Good price on the VV3 express kit, however, Just under $24; 101vape is just under $26
I will probably go for a mod with replaceable batteries next time - still gotta figure out what it is.
Good luck - lots of resources here to share the knowledge.
