HBox doesn't use virtual renders so I'd actually recommend a List based control like HorizontalList. You may also want to use Ely Greenfield's SuperImage to avoid flicker when scrolling.

Thanks, didn't know about the list controls!

Use a TileList. It can use ItemRenderers which uses fewer resources.
