Let me see on my "no interest in" list would be.
lanyards - hate anything around my neck, I don't do necklaces or even coded head phones for the same reason.
Auto batteries - please, one carto leak and, they would be shot - push a button for crying out loud.
Funky flavors like tuna, beef jerky, cheese - lave me to my tobacco, fruits, nuts, coffee and, chocolate please.
Building my own mods - I love many of them others build and, have a small collection but, I don't care to build my own - just need to find someone to do that Dremel Tool mod for me, just to have it for the novelty of the thing.

Also want a builder to make a light up box mod out of my now non working Razer Death Adder Mouse - it's the Dragon age one and looks cool, would look cool as a vapor spitting mod LOL.
