Haoda and Katz Eye both make screen for 400D which the user can install themselves with a little effort. Biggest issue to note about these will affect anyone using relatively slow lenses (f4, f/5.6) and who prefer to use Partial/Spot metering, as the screens affect metering accuracy...someone on POTN has reported as much as 3EV error with the 40D in using the aftermarket screens.

So, Haoda and Katz Eye may not be viable either... at least in solving that problem.
