Rear door needed, advice on sourcing

Need a new rear/back door for my 110 as its rotten and flaps about too much. After looking on ebay the choice is huge.

I see second hand genuine doors going for over £300 and new pattern parts starting from £100.

It wont need to take the weight of the spare as planning a swing away carrier for that, untill i get one it can stay in the back of the truck.

Vechial was repainted in the last year and i have some left, so in an ideal world i would like a glazed door in primer.

Can anyone comment on the quailty of these cheaper doors?

Heated rear not needed.

Thanks

I got one with a heated screen from a place in Liverpool, I think it was £135, It fitted a treat, I fitted a chequer plate panel on the inside, but buy a blank and fit it yourself other wise the cut outs for wiper motor and door lock are in the wrong places. Worth all the work, the previous one had cracks all over the struts on the inside due to the rear wheel being fitted on the door, don't forget to Waxoil it as all the insides on the struts are bare metal.
