I used to have the play+charge kit, but I had three batteries and now they're all completely dead, won't hold any charge.
Now I use actual rechargeable batteries (2500mAh Energizers); each charge lasts longer and will last many more charges than whatever cheap AAs MS puts in their rechargeable packs.
Cheaper initial cost, too - a fiver (£5/$10) for four of the aforementioned batteries, whereas it's £10/$20 for a single rechargeable pack plus cable.
