I've been having good luck with Mt. Baker Vapor juices, tried them after reading lots of good things on these forums. Inexpensive, liked the flavors so far, you can add extra flavor shots for 25 cents if you like your flavors strong, fast shipping, and I've gotten a free flavor sample with each order so far. Can't beat that. As far as clearos go, I've been having good luck with T3's and the Protank. Both will work just fine with your eGo style batteries, and I think the bottom coil design is less hassle than the top coil your CE4's use, no tipping when the juice gets low, etc. The replacement heads are pretty cheap for both as well. I'm still experimenting myself, have some EVOD's on order to try, and picked up a cheapo carto-tank at the local vape shop this afternoon to give that a shot. I noticed you said you would be interested in a PV that lasts you a few days. My Innokin MVP arrived on Thursday, and just on the initial charge out of the package, I STILL haven't had to charge it, and I vape alot. Pretty impressed. It's a box mod, though, close to the size of a pack of cigs, so that may be a turn off if you like the eGo style. Just throwing it out there.
