my Brunton Duo Range/Grille finally came in at REI today... you can read more about the features here:

first impressions are not great... the overall assembly quality is horrible. i couldn't even get the lid open at first becuase it had slipped up under the stove top main body and i had to bang around some to get it open. next the main top wasn't tucked inside some of the slots that hold it down. so i had to take all the screws out, tuck everything in where it was supposed to be and then reassemble. also had several dents and dings in it even though the box it came in was perfect.
overall i still like the size and features and i'm going to test it out this weekend. it lights perfectly well and makes very even flame on propane, didn't have a butane cylinder around to test it with.
going camping this weekend and will use the crap out of it and post back the real world results. no, you shouldn't have to deal with poorly assembled junk at these prices, but in the end if it works well then i'll still keep it!
