I haven't completed mine yet and I am waiting on glass to come in but I would caution on a 300g plywood for cost reasons. Brand new they can be had for 1200 or so from glasscages and I'm sure other places.
I originally quoted myself prior to getting materials at nearly 1900 for my 12x4 garage build but I am currently 600 over budget due to purchasing things I didn't think of or miscalculations or going with a better version of something. Cost can snowball pretty quickly. Glass was 280 locally for a 2x8 piece, epoxy ran me 250 for how much I needed. If your staying a moderate size then go glass/acrylic.
