IMO Everything NICKSTEEL has been advising you the entire thread is spot on...start out with a vision spinner 1300 mah ($25) or an ego twist 1000 mah ($27) both are very well built, easy to use, are compatible with a wide range of sizes of clearos, tanks, last 1-4 days before recharge (obviously dependant on ur daily use, my twist lasts me 2 days, spinner 2.5 days) both models use same charger (standard ego usb charger, make sure u also buy a usb to wall adapter)
...as far as ur clearo/tank mini viv novas would be my first choice for you, they are very simple to use, refil juice, and pop in a new head (after 3-4 weeks when old one burns out). after studying this forum, it is by far the most popular clearo for noobs & moderate vapers. I know you read a thread or two about the tanks cracking, that is true, it can happen, but the reason for that is there are about 5% of juices out there that contain a certain flavoring type, ie. cinnamin, citrous flavoring...most good juice sites will warn you which ones, have a list on their site, or do a simple search here on forum...Another main clearo/tank is the T3, MT3, Kanger T3 (all basically the same exact thing)...from my limited experience using them and my research on here my opinion is they sure can be great, but don't seem to be quite as "stable" as a vivi nova...a few more leaking/gurgling issues with them...more for someone who's been vaping for 3-9 months so you can understand how to tweak them to avoid leaks/gurgling.
when chosing for a juice vendor, make sure you atleast check out Mt Baker Vapors, u can customize every liquid you buy ie. 80/20, 65/35, 50/50 pg/vg (standard is about 70/30 pg/vg give or take 10%), you pick how much nicotine u want ie. 0 6 12 18 24 32 (noobs prolly need 18 or 24, I use 18), u pick out what size bottle you want...they ship same day (even on Sunday) have GREAT flavors/selection, and their prices are better than reasonable!...
for ur hardware I use ALTsmoke, been around awhile, they've done me well, but look around, there's hundreds of vendors for juices/hardware...
