What item in comics would you most like to have?

lantern ring? thors hammer? the invisible jet? something else? take your pick

The Force

                             Jack Knight's Cosmic Rod 
 
 
               

The Infinity Gems

THE HEART OF THE UNIVERSE!!!!!!!!!!!!!!!!!!!

"The Infinity Gems "

An orange lantern ring could prove quite useful. 

Cyttorak Gem 
Green Lantern Ring

Surfers Board 
or 
Thors Hammer 

Staff of One, Gungnir, Green Lantern ring, Wonder Woman's lasso. At least thats what I feel like today. 

Iron man armour
Green/Blue lantern rings
Power Cosmic
Mjonir

The Infinity Gauntlet, a Cosmic Cube, Eye of Agamotto, Helmet of Fate, the Quantum Bands, Green, Red, Yellow, and Orange Lanterns and rings, Thor's Belt of Strength, Hellstorm's Trident, Dr. Strange's Cloak of Levitation, some Terrigen Mist crystals, the Star Brand, and the Venom Symbiote!!!!!!!!

Just one item...? That is very, very tricky.
 
Probably Randal Dowling's unencrypted hard drive. Why get all sorts of crime fighting gear when you can get comic book science that works in the real world? Think of the possibilities. The fame. The prestige.

Any of those...

" @Deadcool:  That's BRB's hammer, Stormbreaker. Not Mjolnir. lol.  But, give me the HoTU. "

In this order 
 
Thor's Hammer
 
Infinity Gauntlet 
 
The Anti Life Equation (if you can call that a thing)
 
Cosmic Cube

" @Deadcool:  No, I don't. =P
 
But I thought that was a different version of this.   Thanks for the correction. "
