Yep, it's a 'spec me'. Didn't want to join the horde and include that in the title tough. 
I'm currently looking for a large bag to take on holiday with me; preferably one with wheels, etc. Ideally, I want the thing to last. Durable is the operative word here. That, and practical.
Now, being the noob I am, I'm unsure of how many litres I should ideally be looking for. My guess for a week is possibly around the 80-100 litre mark?
Secondly, I'm unsure of it's worth spending lots of money on such a bag. I've had a cheap tacky thing in the past for about £20 but it broke almost immediately and my mother is adament that paying large sums is pointless as she's had 'expensive bags' in the past before which still just end up breaking and it's better to get something cheap anyway.
So, any suggestions and/or comments regarding the above please?
TIA.
