I setup Comfy UI LTX 2.3 and was actually able to get it up and running via assistance from CharGPT in under 3 hours. Now I have gone and added hosted gpu services for about 1$ an hour using an Nvidia 40S series with 48gb of memory. Rendering times are blazing fast. Well worth it when you building with 15sec clips at 1080 or higher resolution. Much cheaper than any other option.
