Honestly Steve, everyone here wants you to succeed and a lot of us here have over a decade of experience and had gone through so many tanks and stands through out that time. Everyone had their share of DIYs, successes and failures in keeping marine life that just wants to guide you in the right direction. A lot of people start and quit this "hobby" quickly because of failure, finances and most importantly - failure to listen to those that are already successful and know what they are doing. Nothing in this hobby is by accident. Again, I have never seen a lfs that build their stands entirely out of plywood. My point is that the stand is not something that you really should compromise with based on price or budget or a really super cool elos design. There will be people viewing your tank that will be up really close to it. Name it, kids with their nose or face directly touching the glass looking at the inside. They'll be like "wow, that's nemo" then bam, your aquarium falls in the floor. Can you bear the risk of having your tank collapse in front of people? Most people use 2x2, 2x4 and steel stand for good measure. I've used all of them and they helped me sleep better at night. I'm sorry. I know you are a newbie and probably think that getting the coolest equipment or technology such as an LED fixture that simulates lighting storms will help you grow sps or get an advantage over other reefers but it is simply not true. I still use metal halides because I know they work. Radiums really grow corals, has all the light spectrum to grow anything you want and is tried and true. Money is not an issue to me and I could have replaced all of my lighting with the coolest technology out there but I don't because I know what works best. I would use 2x4, 2x2 or steel stands because they work. Reef keeping is not cheap and any cost cutting you do will end up biting you in the end. If your plywood stand fail, you'll realize the additional $200 it would cost to get that steel stand was not a bad idea after all.
