I have purchased 4 torches for use with my Lotus. The Sleek Honest, a Zico (The one listed above), a Jobon trigger-style torch (ZB-529) and a Jobon "premium torch".
My sleek honest torch (video posted above, listed as the vector volt) does the job, but sputters out. I spent a long time looking for a trigger-style torch, and settled on the ZB-529. Really nice looking torch, but unfortunately the flame doesn't come to a sharp enough point, it's also causing black soot to form on the Lotus plate, so I don't use (that was a waste of $15!)
My Jobon Premium (no model number listed on the ebay auction) works well, no sputtering, but the tank holds only enough butane for about a day of use! I have since been using the Zico torch as my main torch for the Lotus - holds a fair amount of butane (3 days worth), nice to hold, and doesn't get too hot to handle.
My next torch purchase will be this one:
http://www.ebay.com/itm/Jobon-Weldi...rch-Jet-Butane-Gas-Pipe-Lighter-/111172177162 - from what I hear, it can hold a week's worth of butane! And I like the adjustment valve on the bottom - easy to adjust without lugging a tool around.
Purging supposedly increases the performance, and allows the lighter to hold more butane (you'll want to do this, trust me, otherwise you'll be refilling your torch OFTEN). That said, in a pinch, I have simply refilled my torch without purging the butane first. It still functioned just fine. But normally, I purge so I can hold more butane.
