I'm down to $110.40 for all the brass hardware excluding the miscellaneous brass screws/nuts/washers for various odds and ends in the base. I have a feeling those will add up as I'll have to purchase more than I need of everything... It's still gonna cost over $300 when all is said and done (adding in the power supply, other components, the wood and stain, router bits for my dremel, and miscellaneous brass screws/nuts/washers). So it's gonna be close to $800 total, or if you include all my other equipment upgrades close to $1000...
At least I've been able to find some cheaper sources, and cut out unnecessary extravagance. That's saved over $100 already!
