I had this years ago. Useless thing that barely had enough room for a single breakfast and kept trying to fall over. I thought it looked cool at the time. Read the other comments and avoid.
This is bad info fella, maybe edit or delete.
I do agree, but there is something to be said for the neatness and convenience of the canister type. You absolutely have to pay for that though. The problem with the CV model partygrills is that you really are committed to the canisters - the best options have flexibility to go both ways - personally I have a Cadac Safari Chef 2 with regulators for both Calor and EN417 canisters, so I can be economical if using on site or have a lightweight option for beach/park/whatever use. For anyone wondering about economics, these Campingaz CV470 carts work out to about £11.50/kg, Coleman C500 carts as used by some other similar stoves are about £10/kg............ the larger Campingaz 907 (2.7kg) that many people use with their camping stoves are actually pretty rubbish at about £11/kg, while Calor or Flogas 4.5kg butane refills can be as cheap as £4.50/kg.
BAD INFO ALERT! Those Coleman 500s WILL NOT work for the Partygrill. You need Campingaz's own CV470 - it's a different fitting (Campingaz Easyclic vs EN417 screwfit). There IS NOT an easily available adapter. Your best bet is Wow Camping with a 4-pack at £17 (or 12 pack for £50) + £4 postage or Argos at £20 for 4 with free c&c if you have a convenient branch with stock. Also ebay options around the same price give or take a pound. Careful not to accidently get CV300 which are smaller.
