How much should I spend on a cd player or universa

I am looking for a cd or cd/dvd player. Based on my equipment listed , how much and for which units would fit my system as far as quality compared to the rest of the system. ( basically , If you have a 100.00 system, a 5,000 cd player would not sound any better in that system than a 100.00 cd player.Also would I be better off getting separates or single player to do both jobs.
