Lawn edging

Any recommendations? I was looking a plain steel 150mm deep but they want 250 for 20m. I see https://www.greenfingers.com/p19066/everedge_classic_lawn_edging_l5m_x_h75cm.aspx with spikes which would cost me 160 for 20m. Anyone used it or other source? Thanks.

Yes I’ve considered this as well, I’ve thought about finding a cheaper source, perhaps need a fabricator or someone, if that’s the right term/job

I got some recycled rubber ones from Greenfingers with the spikes etc. As I'm a bit belt and braces, I just wanted something that would last and do a good job. The lawn edges are cut with shears so there's no catching them with a strimmer wire.

I had them, only lasted one season, they broke up into shards
That is why I went over to wood and metal ones
I have the wooden ones to separate the grass from the pathway and the metal ones to separate the grass from my planting area (I have blueberry's and beetroot there)
I have solar LED lights on the wooden ones
The metal ones are 1 meter long by 200mm high
