Rail mounted Table

Jarodjay

I am looking for a rail mounted table. I see that I can get rail mounts from Magma. I think the Docktail tables are really nice....but also really expensive (https://docktailbar.com/collections/bowriders-deck-boats/products/docktail-utility-table). Two questions: Does anyone know of an alternative but something simlar? Also, are there websites, besides ebay, that list used boating items?
Thank you in advance for your help.
