I'm definitely a do-it-yourselfer. I'll build my own workbench than buy one at the hardware. Same with my kegerator. And it is the reason why I wired and installed all of my new home theater components. However, with all of the hobbies and commitments I have now, I don't know if CRT-tinkering is another one I should start. I know this Vision One/Marquee 9500 is/was top of the line and I want to keep using it, but I don't have the desire to keep throwing money into something I don't know I could correctly maintain myself.
On a related note I have a Vidikron Vision One for sale - has an HDMI card. Comes in black.
