L30WB I've had this for a few years now and it works very well for the intermediate beginner products I make BUT replacement tips for lenk wood burners are VERY hard to find. several online resources, but all contain only one "universal" replacement tip. They're pretty SOL if you need a cone tip, spike tip, etc. You can order replacement tips directly from Lenka BUT they want you to pay taxes (your local sales tax) AND $10 shipping! If you don't want to buy tips to resell them, it's not very profitable to spend more than $16 for TWO tips, more than $22 for four tips, etc. I strongly recommend considering another manufacturer.
