Home Cinema Upgrade

I'm looking to add a DVD Player to my current system. Budget is aound £600. Which of these three options is best:

1) Add DVD Player and Subwoofer to current system (Technics Pro-Logic with 6ch Dolby Digital Input, Front: Total - 160W, Centre: 120W, Rear: 60W.

2) Buy an All-in-One DVD System such as Sony DAVS888 or JVC THA75R

3) Buy Seperates (if so, what do you recommend to fit within my budget).

Thanks.

Get some separates, Richer sounds are doing the Marantz 5300 reciever and Eltax evolution speakers for £390 which will leave a fair few quid left to spend on stands,interconnects,speaker cable, and the DVD player,etc. Here's the link
