Welcome aboard!! Take your time, research all the builds you can, be sure to ask the community anything you need help with. There's a lot of knowledgeable folks on the site that are glad to help. And, don't buy anything on ebay unless it's from a member from here. Most anything on ebay is not accurate or made with quality materials, and don't buy anything from anyone on FB unless you can verify they're legit. There's plenty of venders that make high quality props and pieces on the the site here...
Enjoy the ride and be sure to post your progress pics, everyone loves to see the build threads and it helps everyone to learn!!
