I have this Twister 270 stove kit:
Pros -
- cheap
- packs away neatly with the gas cannister inside one pot and that pot in the other pot
- use the smaller pot as a large mug to save weight
- CV270 gas cannisters are sold in most camping shops
- clean and easy to set up and use
Cons -
- pots are aluminium, although they seem to have a coating
- gas supply fades as the cannister becomes empty, although I don't tend to use it much on full (it's quite fierce)
- not very stable, although three tent pegs can be used as mentioned
- the stove is quite heavy
