MTB Bag/Case Recommendation

Ok Ladies and Gents as the title says I need your recommendations, thanks for any help you can give
It depends on the bike, I have a bag from chain reaction fits a 26 but doubt the 29 er will fit in. If u have lots of cash get a hard case especially if u have an expensive bike. The way u pack it is as important too. Also any box from the lbs will work too
I got hard case from my coatch for a track bike - could fit my 29er there (M size frame), just had to take off brakes, fork, deflate tires etc... anyway, managed to fit it there, so can ride it here :)
