Welcome to ECF! Vaping will change your life for sure!
As the others have said there are many different choices for e-cigs as well as a multitude of different PV's (Personal Vaporizers) to choose from.
if you are not liking the cutoff I would highly recommend going to something like either a 510/Dura/Yetti style PV that has a manual button.
Basically it fires the atomizer as long as you hold down the button, the 510 style atomizers produce a good amount of vapor.
Also a DSE 901 style PV has a 7 second cutoff on it, in my experience this is more then enough time to get a good strong hit off of it, and 901 atty's have awesome vapor production, you can get past the cutoff on these 901's by slightly pausing before you hit the cutoff... I doubt you will be vaping for 14 seconds straight.
starter kits for both styles should set you back about 45 to 55 dollars, depending on where you get them from.
there are also a ton of Juicebox style mods out there, as well as larger full size mods for the 80 to 130 dollar range that offer so much more in terms of warranty, quality, and performance/Vapor/throat hit.
Read around the forums and you will get a good idea of what is available.
