I think there are really 2 options here. The CTEK MXS 5 and the Noco Genius 5. I have the CTEK, but if I had to do it again I would buy the Noco. Reason being is the Noco can initiate a charge if your battery voltage is between 0 - 1 Volt (your battery may ultimately be f*$@ed, but at least you maybe able to start it to get it fixed or you may have just left your lights on with a relatively new battery). The CTEK will only register down to 2 Volts and then will decide there is no battery and won't do anything (This I know from experience).
The Noco will also charge Lithium Batteries (provided the batteries have their own BMS), the CTEK will not.
Price wise, I think the CTEK comes in around £90-100 and the Noco I've seen around £80.
Note. Don't be tempted to get a 10Amp charger. As far as I'm aware, that era of Aston runs a 10Amp fuse and I expect it will be a tad annoying if you blow that.
I have the Aston one (got free) and also use the CTek MSX 5, both are good.
