For your PVM all you need is a RGB cable (specifically meant for the model 1 since that has a different size plug than the model 2) from a company like Retro-Access.com or retrogamingcables.co.uk. I would suggest you get the one with a stereo audio cable going to the front to get stereo sound (stereo only works from the front headphone port, whereas anything plugged into the back is mono sound only- SUPER easy to mod the Genesis for stereo out the back if you're a DIY kinda person, and definitely a cleaner way to do it instead of a wire leading to the front which annoys me).
For your big ass consumer CRT TV, that would need the Shinybow SB-2840 RGB to Component converter. You could also get the HDRetrovision Component cables as well, but those kinda suck since they're like $50-60/each, are commonly sold out for months upon months, and are only available for a select few systems – whereas the $75 Shinybow will work on any RGB console (which there's a ton of), and is simply a much smarter device to invest in if you have (or have any plans for the future) on running a bunch of systems on your consumer TV.
