Iron on edge banding - is cheap any good?

[Simon89]

I am looking to buy some iron on edge banding for finishing the edge of some 18mm ply before painting.

Looking on ebay, real wood edge banding seems a lot cheaper than I was expecting; ≈ £10 for 20m inc postage.

Is cheap ebay edge banding any good or should I be looking to source from a more reputable suppler? if so who?

Thanks
