I bought a GBX75 in October for £129 - silly price for what you get, but sometimes that's how it goes with Amazon. Never had to use it on my own vehicle, it's started some cars with seriously depleted batteries - just. Just is often good enough though.

I'm sorry but why would anyone pay that kind of money

I purchased a starter pack for £35 ish, its never let me down over 3 years, it was advertised to start a 7 litre petrol engine on eBay

Yep it's like buying a Range Rover, silly money, lots of cheaper cars on eBay. Needless to say I have a big Nobo I've never used it but it makes me popular with others.  Geoff

Halfords are doing Noco at this price too if you are a member of their free to join motoring club. The Gb70 is £178 after discount. Amazon can't ship Noco to Northern Ireland but Halfords stock them.
