I haven't done it but it is my understanding that the results can be excellent. The one thing that held me back is the fact that the $300 that you are quoted is most likely just one input with each additional input you do costing extra. When I first purchased my TV I knew I was staying with that connection type so I decided against having it done; I am now using the best input for TV but I haven't given it a thought...now look what you've done!
