I have the GSI Hard anodized boiler. It's a good piece of equipment. I use it together with a stove / stand from the mini trangia.<br><br>The only beef if have with it is I still can't get out some of the scrambled egg bit at the side of the cup! <br><br>I had a hard time deciding between the GSI boiler and the mini trangia so I bought both. The stove / stand of the mini Trangia is kind of heavy compared to a home made alcohol stove, but I like the reliability of the trangia.......<br><br>
