A friend gave me this one, he didn't use it much, and it sat in a drawer after that. I can see it spark, and I can smell butane when it's switched on, but it won't always light. I have started it, and it vapes fine once it starts. I am above 5600 ft., manual says that may cause problems, I don't know if that's it or not. I notice if I turn it on, it helps to blow in the screened area, like it's dispersing the gas in there, then it starts. How about $40 shipped? It's completely clean, and comes with the accessories shown. Quick, discreet shipping to US destinations included.
