Laptop you selected is great, but I do not think you can get all other with £1300. If you do not play latest 3d games, you can get a cheaper laptop, from say tiny.
Another thing, you may need to buy from differnet places.
You may need to give more details for other items you want.
The best place to buy digital cameras click here, a lot of satisfied customers here, only problem is that it is a French campany, so you may get a French manual, English one can be normally downloaded and printed. Do not buy memory card from Pixmania.
The best place to get Camera memory card is Ebuyer click here. It is also a good place to buy External Hard Drive Cheapest one 200Gb £154.88 click here.
Wireless router with Buildin Adsl modem can be found from Ebuyer, but a better place is broadbandbuyer click here.
