Before I buy the Pro tank 3 can you give me a estimate cost on a 5 pack of coils please. I really like the way most of the coils work on the P.T.2 but my slight problem is that I use 1 to two coils each day. I'm approaching the 300 coil mark and it is a bit pricey for me. Not complaining mind you because the joyous feeling of filling a tank only one and a half times a day, being able to use a simple spinner type device and mostly getting that wonderful draw and crackle hit I absolutely love is worth it. So my question (and I do realize it's possibly a bit early) Do these P.T.3 coils perform as well? Are they lasting any longer for YOU! vs. the P.T.2 coils? That's it! Thanks
