Why aren't there more Blu Ray/DVD transports?

I really don't get it. If you have a great pre/pro with excellent Dac's then why do you need to pay twice with a player that has Dac's. I have a nice 2 channel system and would like to complete the home theater experience for the family and for entertaining and I would like to keep the home theater on par with my 2 channel or at least close ( I don't know if I can afford or want to pay what I need to match my 2 channel). However when I start researching I get a little confused and irritate by this market condition. I hate to pay for something twice.

Am I missing something?

I use a Sony BDP - S301 for playing CD's after my Marantz CD67 expired from old age. I paid $10 + $11 shipping from an eBay auction! I was the only bidder! Why spend big bucks for an Oppo when a quality player like the S301 is at least as good sonically!
