Both of the pieces in this build I bought. Don't bid on them because people like to make other accounts and bid on their own stuff (highly illegal) especially on stuff that doesn't sell super quick like driftwood. Occasionally You can find a good deal I got a 20 gallon fish tank off of craigslist for $50 and it had well over $200 worth of equipment and supplie, including a brand new unopened t8 fixture with 2 bulbs. While at the same time I've seen tanks with much less inventory have $200 asked for them. It's all a matter of being in t right place at the right time, just like driftwood. Or like this rad piece I found down at the river below...
eBay search cholla wood. Cholla wood looks awesome, can be found for super cheap, and I have a tank that has had multiple pieces in it for over a year and they look great. But like I said, you can get awesome wood for cheap, just be patient and don't bid on it just go ahead and buy it. I looked for over a month for the wood in this build.

You can get the stuff that's $100 on eBay for less than $50 more often than not. $30 will get you some SICK looking driftwood manzanita or red-moor too. Hope this helps. All info is thanks to other people's advice and LOTS of time researching and googling.... Girlfriend says I'm addicted hahah
