If your looking for a cheap route , I went to the grocery store and purchased a big can of tomates , emptied them out.

I used three large screws for legs with a nut on top and one on the bottom...the inside nuts keep my screen and coals from touching the bottom of the can.

I evenly spaced air holes all the way around the can and placed a feeder square at the top of one side.....medium size twigs will self feed. and the feeder hole doubles as an air vent for when you use a big cooking pan.

I bought one of those wire mesh clam shell things with the long handle on it from wal mart , cut the bottom half of it off and trimmed it to fit inside on top of the screws , it holds all of the fuel and allows air to get under it.(the fuel)

I used the top half of the ( I think its for toast )wire thing with the long handle as the grill surface and it has a long handle on it as not to burn your hand I think I paid 4 bucks for the tomatoes , 2.95 for the 4 screws , and the wire toast thing was on sale for 3 bucks.....10 bucks and I have had the ugly duckling for well over a year...I did paint it camo for the fun of it recently.....I know on long kayaking trips it has served me well , very well and people laugh at it until it warms them.
Thanks for reading my first post.....
