I thought you'd decided on the Mosaic Quad?

Of the two, I'd probably go with the Travelpro (regardless of the downward-spiral of their warranty service). The Marquis line is mostly an aesthetic variation on the same general build as the Crew line (same wheels, handles, etc) and generally well built. It's a fairly notable step up in build quality from the Maxlite lines. I'm not really a fan of single-wheel casters on spinners but Travelpro does have the most robust single-wheel design I've seen. The wheel design of the Samsonite looks to leave a lot to be desired.
