No idea what cross fading is but buying flashing lights on ebay cannot possibly represent a bargain in any sense of the word as it sounds like your buying someones second hand chtistmas decorations.
I had £120 stolen from me through Ebay last year, I'm still a little bitter about the whole thing.

If you'd posted on any other subejct you would be suprised how cheerful I can be now xmas has finally passed

But it will be devoid of meaning so i wont mind.
