I'm planning on taking my wife camping for a weekend with view to go for a week in the summer.
I have never been camping and am unsure what tent to buy.
I don't want to spend too much, I have around £120 to spend for all the kit I need for the weekend, plus I will be travelling on public transport so I don't want it to be too big or heavy.

I am considering either http://www.halfords.com/webapp/wcs/stores/servlet/product_storeId_10001_catalogId_10151_productId_745405_langId_-1_categoryId_236909 or http://www.halfords.com/webapp/wcs/stores/servlet/product_storeId_10001_catalogId_10151_productId_745457_langId_-1_categoryId_236902 or http://www.halfords.com/webapp/wcs/stores/servlet/product_storeId_10001_catalogId_10151_productId_745521_langId_-1_categoryId_236906

Any advice would be greatly appreciated.
