Hello, I'm new and happy to be here. My name is Jeff. I know the first bit of forum advice is always to "read the posts" previously, but, please understand, I have a debilitation medical condition that prevents me from sitting for more than 10 minutes at a time (vascular/lymphatic disorder). So, I can't do that. What I would like some help with is if anyone has a great condition/mint PH50 for sale, I'd like to purchase one. Also, if there are any video comparisons of the PH50 and the Abyss anywhere, I'd like to see a good video. Can you all send me a link if that's possible. If I buy a PH50, are parts and support still available? Also, would like to see Abyss in Spot and Diffuse attachment in video too if they are out there. Thank you so much.
