Rocks and Driftwood

[meegosh]

Hey guys,

Quick/dumb question... some of you may know that I have plans for a 30 gallon long. I want some rock caves/driftwood pieces in the new tank to make things a little more natural looking(compared to my hot pink-muli-colored-hippie-type gravel i have now).

Do you guys find your own rocks and driftwood? If not, where do you buy them? I found some decent pieces of driftwood at Pet Supplies plus but they wanted almost $30 for a foot long piece. Rocks were $10+ for a decent size one (small dinner plate).

I found some rocks on ebay, you think these would be any good?

Also, I am not going planted with this new tank. Should I stick to a gravel substrate or go with sand? I've heard the downside of sand is you have to be careful when you gravel/sand vac (suck up sand, clog sink, etc.).

Any thoughts or comments?
