So my Model S arrives just as Ecotricity brought in their £6 for 30 minute charger. There was one near my house so this is a real git. I am therefore frantically trying to work out my home charging solution. I know I want 32a tethered product so that bit is done. On research I have found these options (I think)... Rolec - £199 (do I need to buy a Tesla cable or will my car have what it needs? Pod Point - £650 - same questions as above plus why so much more expensive?? Am I missing something! Chargemaster - £279 (I think) - same question as above Tesla's own - £££ as no grant yet. Some help would be very appreciated please!
