Yes, EAA is worthwhile, but it can plunge you into a deep money pit...
First, you get the excitement of seeing stuff that you have never seen through an eyepiece. My seeing conditions are so bad (light pollution) I struggle to see the Orion Sword asterism with the naked eye. Not a hope of seeing the Horsehead even with a 8" SCT, yet I had it on screen inside a few minutes with a camera. Dave's images (Post #3 and #4) are typical, but I would need a remarkably good night to tease out that clarity of detail and I tend to 'observe' rather than 'image'. EAA will beat serious light pollution.
You then get sucked into the allure of sitting indoors in a warm 'mission control' remote controlling everything. The obvious solution is wireless, which is harder than you think with a high resolution camera. Then you fiddle with 'active' USB and find that distance is a problem. Then you try a dual computer wireless route. Then, you get obssesed by 4K UHD and end up with Cat6a cable. It can be a very deep money pit if motivated to find the ultimate solutions as I have been.
One thing I have learned as a technology fanatic. Sometimes, you need to arrest ambition until other technologies catch up. For example; in pursuit of the 4K UHD dream I spent big bucks and succeeded. It is wonderful to have the greater depth of zoom possible from higher resolutions, notably when using Hyperstar when you are 'observing'. But if you are an 'imager', why not simply 'observe' in 1080p and 'save' in your cameras native 4K UHD for later post processing of your region of interest? The reduction in system load possible by dropping from 4K UHD to 1080p is dramatic and that then makes WiFi connectivity possible and costs tumble steeply.
In summary, EAA is fantastic, but you need to make up your mind if you are primarily an 'observer' or an 'imager'. Once you have settled on the latter, DON'T (for example) pursue the 4k UHD dream. By 'observing' in 1080p even if you still 'save' in 4K UHD you will save enough cash on equipment for a holiday. But it is nice as an observer to have that extra level of zoom, but is it worth the serious extra expense, perhaps not.
