I bought a Zen Mk1 for £250 from Ebay earlier on this year and it's a doddle to use, pop a cd into the Zen and four minutes later it has been ripped to the hard drive on the Zen and you can then listen to it by streaming it from the Zen to my amp, I use my iphone (or my laptop) to select music via an Ipeng app (£10) or a Logitech Media Server webpage on my laptop.
You can also play CDs from the Zen if you hook it up to a dac>amp.
I also bought a Yamaha R-N803D stereo receiver which streams music or plays FM/DAB radio or internet radio, turntable & TV, the yamaha amp has Musiccast built in which allows you to stream around the house to speakers etc or you can stream to it via the iPhone etc, very simple and decent sounds, there's also a Musiccast app for iPhone which I use to control the amp and play whatever I like from it including vinyl although I have to put a record on the TT for that
plus you can stream vinyl from the Yamaha to a music cast speaker or another Musiccast amp.
Hard to believe that inside this little box (Zen) there are over 500 CDs stored which is only about 10% of the total volume of the hard drive in the Zen but funnily enough I have the zen set up in another room away from the hifi and all of the CDs are stored in about four 20 litre plastic boxes in the same room.
