Bike bag recomendations from the following please:

I'm looking at bike bags, browsing Merlin and CRC. I could do with keeping it around the £100 mark. Looking at the Ultrasport or Richey on CRC http://www.chainreactioncycles.com/Categories.aspx?CategoryID=551 or the Merlin own brand bag http://www.merlincycles.co.uk/?fn=category&categoryId=126. Any advice for me? Do those bags take the wheels too or do they have to travel outside the bag? It'll be a full sus medium frame.
Thanks
