^Beat me to it^
Id get AV'd first and see what pops up in the Sales thread. But if you want an opinion from those three Id go Carbine. Long enough to be fun outdoors as well as short enough to use for indoors. The Light is pretty short imo, not saying you couldn't use it outdoors but I prefer a larger rifle for that type of play. Also see if you can't get out to a game to try out some, after all you don't want to spend $300+ on something that is uncomfortable/awkward to play with.
My only worry about death is that my fiancÚ will sell my gear for what I SAID I paid for it.....
