Congrats on your move to the wonderful world of vaping. I started probably 4-5 years ago when the very first e-cigs came out and I never looked back. Ego style batts work well for beginners, though I would def recommend going with a VV/VW. Also, I can't say enough about Kanger's tanks (EVOD, ProTank 1/2/3, ect) They work soooo good, and the heads are easily rebuilt. (If you have any intention of rebuilding the heads then stick w/ single coil options as they are less tricky to put together, I prefer the singles anyhow...)
1. EGO spinners are a good low-cost option (also small in size.)
2. Innokin iTaste VV 3.0 - low cost, smaller in size than an APV/Mod, is VV (3.3-5v) as well as an Ohm tester, should you rebuild your coils (highly recomended)
3. If you don't mind going bigger in size:Vamo V5, Sig ZMax, iTaste SVD (the MVP / VTR are great as well, though I prefer a round mod)
**just ordered an SVD from kanVape.com. Have not purchased from them before, but I couldn't pass on their price. Will see how this order goes. The SVD express kit is $42.95, and they have an offer on their site for 20% off you first purchase, so $34.36 w/ discount AND free shipping. (The coupon was not working for online checkout so you have to call in to place your order, though well worth it for the price.) $20.50 for a 4 pack of IMR 18350 batteries + 10.50 for Nitecore (free shipping for everything- Amazon) Total= $65.36 Not Bad
