Mangrove Roots/ Manzanita Wanted

[piper]

I want to rescape my tank with a mangrove root style. I just wanted to know if any one knows where I could get real mangrove roots from rather than the resin fake ones shown below.

I've seen some twisty driftwood pieces on Ebay in the same style as the pictured one.

Likewise, manzanita pieces are very branchy.

Been looking at manzanita but can only find american webbys that sell it and none on ebay. Do you know where in the UK has some ??
