Here's a great little roller bag kit that normally runs well over $200 dollars. The kit can be separated into two separate bags or just used as one padded roller. The small roller can be emptied to hold clothes, and a padded insert can hold a camera body + lens with two additional lenses and room to spare for a laptop computer. On Amazon they are still listing the X50 for $213 (seen here). Currently on B&H they have a huge huge discount dropping the price down to just under $80 bucks via B&H (click here).
