Thanks for the information folks! I do have another mod much like the Copper. I love it because it works after years of hard use, but it's just too bulky. I have had an Infinity and a Buzz as well. There size is much better, but they both have circuit boards for the switch, and I killed both within a year.
The GG looks cool, but there seems to be a waiting list. The REO looks like it's a little more available, but I hesitate since I've never used a box mod. It's kind of bulky and will be an odd shape for me. I'm not worried about bottom feeding or anything fancy either. The Precise Plus looks like it must have a circuit board in it. Are you sure that has a mechanical switch? That looks like it must be true for the X-haler too. Do all those you guys suggest really have a mechanical switch?
Price is not a big deal, but I don't really need a lot of features. I just want to work with heavy use (mechanical switch). Otherwise, it would be nice if it was not too bulky, and maybe use my RCR 123a batteries. I'm flexible of voltage too. Anything from 5-6 volts is fine for me. Thanks again for all ya'lls help.
