There are a couple of bags that I really like.
I have been using the Victoronix 22" for about 4 years of 100% travel and it has never been damaged. Their warranty policy is relatively good - by the way most bags claim to have a "lifetime warranty" but they mean the lifetime of the bag which is only three years. Victoronix has a true lifetime warranty.
That being said, I have been ogling the Tumi 22" Alpha for sometime now and it will be my next bag.
If you haven't checked out Tumi, you really should. Awesome stuff. A bit spendy though.
In my humble opinion, there is no better bag than a Briggs and Riley. Not only do the roller mechanisms work better than most, they typically include little "extras" that make the life of a traveler much easier.
I travel all over the world with my 20" rollaway, or a 25" check-in bag and a laptop case from B&R and I wouldn't replace them with any other product, bar none.
