I've had an L30WB for a couple of years and it works very well for the advanced beginner items I've done, BUT finding replacement tips for the Lenk wood burning products is VERY difficult.
Recommend this product?
There are a handful of online resources but they all carry only the "universal" replacement tip.
You're pretty much SOL if you want a cone tip, dot tip, etc.
You can order replacement tips directly from Lenk, BUT they want you to pay tax (your local sales tax) AND $10 in shipping!!!
Unless you want a gross of tips for resale, it's not very cost effective to spend over $16 for TWO tips, over $22 for four tips, etc!!!
I strongly suggest considering a different manufacturer...
