Wow, just waiting out the weather on temp control devices, was gonna jump all over the ipv 4, but glad I waited, now there is a IPV LI, sigelei and the new Joytech to consider. all will be realeasing new products with preorders now. can't wait to here some reviews on these new baby's, Out of the three the IPV LI looks to be a winner, although you cant beat the realiability of the sigelie or the EvIC vt 60 WATT, Now I am really uptight about going temp control but I keep waiting. I always was told patience is a virtue, hopefully that saying still holds true. Any thoughts.
