When you speak about the value of modifying Pioneer DVD's, you need to speak of those models that are worth modifying. I have a Pioneer 503C carousel, which while working quite well overall as a transport, has developed a number of frustrating mechanical problems over its short life, and would likely not be a good candidate for several hundred dollars worth of mods. I really only expect to get a year or two of service out of this unit and don't see it as a long term purchase. To its credit, it was inexpensive and does a decent job as both a DVD player and an audio transport. However, there are likely higher quality Pioneer units that would certainly provide better value when modified.
