After a little more research, it is looking like a better idea to go with the 3D Hobbyshop 48" Edge 540. It is only $45 more, has parts available, and has much better reviews overall:

Being the same size, I am assuming that many of the recommended electronics would be equally suitable for this plan. Thoughts?
