Recommend me a Lenovo laptop

[JRC1]

Budget ideally £300-£400, main use will be browsing, streaming hd video (sky go/bt etc) and the odd game on Steam.
Needs to have a good battery life and be light. 14-15" display. Not fussed about touch screen etc.

Happy to consider 2nd hand if this opens up the doors to better spec'd devices... has anyone bought refurbed off of eBay and can recommend?

Lenovo seem to have close to 100 different laptops on their website and I don't know where to start!

Probably an ex corporate Thinkpad T450. Preferably with SSD.
I have one at work.
Easy to get Batteries and Spares if needed.

Look for someone on Ebay that has a few for Sale.
