That is my post. I've had that same shrink wrap bag on my etrac for about 5 months. It has one tear on the back which I put some tape on. I'm going to make a video on how to replace it. They are cheap and tough. The 3030 will most likely take a smaller bag? But the larget bag will work as long as you tape up the loose plastic around the back. This wrap has no glare and is tough. They are simply called PVC shrink wrap bags. I bought 50 for about 8 bucks on feebay. It looks like I may go through 3 a year?????
