I'm in the market for an aluminum bumper-style case and have narrowed my choices down to Alcase, the e13ctron s4v hybrid, or a Vapor Pro. Since I'm new to the forums and haven't had time to scroll through the seemingly thousands of pages about these cases, I was hoping to get some feedback -- pros and cons, manufacturing quality, effect on signal, overall design, which you'd personally prefer, etc. Photos would definitely be welcome! Much appreciated, guys! Thanks!
