The highest temp that I run mine to is 330 degrees, although I really like to get the first hit at about 250 to 260 degrees, the hit is very pure and VERY tasty at the lower temps, and you will be surprised at the density of the delicious vapor. I put the cap back on immediately after my last blast and feel comfortable putting it directly on a wood table with the cap on. I have never used a plate or pan to hold it, and the spot on the table may get warm, but heat rises so most of the heat dissipates above the table. Even with the SV1, which did not have a cap, there is enough space between the heat exchanger and the table to keep the table from getting hot or discoloring.
There are nice little pocket torches available on ebay that have a lot larger butane capacity. Search 'Jet Flame Butane Cigar Cigarette Torch Lighter #50003', they are larger than most other torches, hold a lot more butane and will still fit in your pocket.
I am glad to see all the positive comments on this beauty, it is the best I have used and with a little care, should last forever. I am anxious to hear more from the new SV2 users, I think that the more you use it, the more you like it!
