I've bought one recently, the zen vision M 30GB and find it great. I also ordered from Ebay the AV cable for connecting to a TV, usb sync and charge cable and a mains charger unit, all for €30 euro, delivery is a bit slow but need the mains charger before I go on hols next week. Speeratley got a silicone cover off ebay too for €9
I ended up buying a CREATIVE charger in Peats. I didn't have time to buy anything online.
I was about to buy a generic charger in Maplins when the guy advised me not to as CREATIVE have a way of disabling the device if charged from a generic charger. I took him at his word.
For those that have mentioned that they are looking for a charger for their Creatives and are heading on holidays - Virgin megastores have a pretty decent (generic) one for €10 - it also comes with two adaptors one for Ireland and one for Europe (which is handy). It definitely works fine with the Creative V Plus 4Gb.
