Hi Ellen and welcome to ECF. Glad you find ECF before making your first purchase, there many valuable information you can find here. Also the members are very helpful.
I started vaping on New Year, so I"m still learning alot.
He doesn't want to try the fill-your-own cartrige type just yet... he wants one that looks, feels and smokes as close to the real thing as possible, with as little hassle as possible.

Of course we're looking for a great product as cheap as possible too.
Since you wanted something that look like a ciggy, I would suggest Joye 510, KR808D-1 is great too but I have never tried it before. Since you said you didn't want to waste that much money, you will be probably refilling your own cartridge or cartomizer. Cartomizer = cartridge + atomizer in one. (3 pc e cig = battery + atomizer + cartridge 2 pc e cig = battery + cartomizer ) I didn't get much experience with cartridge, didn't like them, because need to top of juice very often. I prefer using a cartomizer instead because they hold more juice. A pack of 5 prefilled/blank cartomizer cost about $8 -$12. 1 cartomizer last me for about 2 hours (depending on how much you vape) So it will be pretty expensive if you just rely on prefilled cartomizer. Refilling them is not as hard as you think it is once you get the hand of it. (*cartomizer are consider disposable, but can be prefilled and use a couple of times) For me 10 cartomizer can last me for about 3 weeks - 1 month

You can also consider the eGo-Tank, filling e juice on the tank is alot easier. But eGo is like a size of a cigar so i'm not sure if you would want this.

I started with a Joye 510, within a week I upgraded to an Riva 510 (Riva 510 is a eGo knockoff) because of the battery life. I would need to recharge my Joye 510 batteries after 1 - 2 hours of vaping. Riva 510 (750mAh) would last me for about 6 hours before needing to be recharge. So that might be something you might want to consider. It also depend on how much you vape.
Here a picture of Joye 510 and a Riva 510 side by side comparison w/ a ciggy so you can see how big they are. The picture is not a eGo-Tank, it's a Riva 510 , but the size is similar to a eGo tank. Also the batteries in the picture of the Riva 510 is 750mah, the 1000mAh batteries are longer. (The battery that is alone, by itself is a eGo battery, the only difference between the eGo and Riva is that the eGo has a silver bank, and the Riva has a gold band)
