Don't worry Emonty I'll volunteer.
First, hello Martha and welcome to the GG Family. You have reached the place where the ultimate device is made.
You might not notice it today, but you need to know that you are lucky.
The AFS is a system that is mounted on special atomizers, that is filled with 3ml of e-liquid (4 on the next generation) and will permit you to vape constantly and non-stop, for hours, without having to top-off your cartridge, or constantly drip on your atomizer.
It will give you the freedom and joy of vaping, without the hassle of refilling.
The AFS is an exclusive concept and invention that you won't find anywhere else.
The price might look high, but it is mostly due to the fluctuation of Euros vs Dollar, since the GGs are produced in Europe. (The shiny part of it, the one with lot of beaches and sun)
Anyway, the price is still very good for the excellence that you get of it.
That brass thing is the button that activates the current on the GG. It might look awkward to you at first sight, yet you will notice in time, that it is one of the most beautiful and distinctive feature on the GG. It is the GG's signature actually.
Not to mention its high efficiency and functionality. The GG button is mechanical, thus will not fail, and it can be locked, which means that a GG will not accidentally fire up in your purse or pocket.
Like i said earlier, the GG cannot be evaluated by its price. You will notice when you will get one, that it is worth much more than what it is priced.
And in all modesty, no Mod can be compared to the GGs yet. Whether in terms of aesthetics, handcraft and built quality, built material, security, functionality, or convenience.
By the way, the smallest e-cig in the world is within the GG collection, and it is the GG Slim.
Specifications vary from a model to another. You can find them under each model description on the GG dealers websites.
Cloud 9 Vaping - Come in from the cold
Vapor Kings - DSE801, DSE901, Joye510 and KR808D-1 e-Cigarette supplies
No. The GGs (except the GG Slim) vape at 6 and 7.2 volts without the need to add anything to them.
You will still be required to have special atomizers if you want to use the AFS.
And you wouldn't want to miss the special atomizers that GG produces, that are especially designed for high voltage vaping, and that can be also used with or without the AFS.
While the GGTS can be used out of the box, with 4 types of atomizers , the 510, 901, 801 and cartomizers, other GGs work out of the box with 901 and cartomizers, thus you will need a little adapter to be able to use other types of atomizers on them, adapters available from GG.
We can tell you anything on the GG, but you might need to tell us what the other type is, if we have to put a comparison....hehe
Anyway, you can start learning about the GGs and get all the info you need from here:

Remember, the GG is here for you to enjoy and abuse. Once you get it, you'll not look back at anything else you previously had.
Enjoy.
