yep, i see no reason at all to sell it. you got it cheap, its takes up very little room, you don't have very many cookers and i bet you will regret it soon as you do sell it.
i look at mine as members of the family so i get really possesive.
suggest you do a few more cooks on it. i have one that i have used twice. being in a wheelchair i find the kettle easier for the bigger stuff though i use my mini wsm much more. but i would never dream of selling the wsm. in fact i gave it a fall cleaning/oiling and put it to bed for the winter a few months ago.
