Those are all great items and you will enjoy them

The paintschemes on the planes are neat and the cannon is very detailed. Lots of moving parts on all pieces.
As for the price, you are paying more for these items than I would pay for them in the US. Given that the current exchange rate hovers around approximately £1 = $2, you are paying about $36 for the cannon and $60 for the dogfight set, not including shipping. In the US, I pay around $15-$20 for the cannon and between $25-$35 for the dogfight set depending on where I purchase them. To me, the prices on your items are too high, but they are correct for Ireland and the UK. (Afterall, when I lived in the UK a few years ago, I payed about $1.60 for a $1 McDonalds Cheeseburger.) So, all that said, it is up to you. You may be able to get the items cheaper from a US seller, but then you will have to pay alot more for shipping. It may be easier just to get the items from a "local" source.
Hope all that helps
