I have no idea, and I really don't care honestly. Thinking about money thats long gone isn't going to help you in any way what so ever. Also the economy is just the economy. Life is far more important. You could save money for years and then get hit by a bus. Do what you enjoy when you can.
On gurbo stuff? Probably around a $1,300. I got lucky with that huge set of US stuff that started me off, and a couple of hundred for the Duo R. Then, it's been nickel and diming the PC-Engine stuff, two or three a month since.
What would "Gurbo" be ? Is that an abbreviation for "Garbage TurboGrafx-16" stuff by any chance?
About a third of that is my US Duo.
It's probably in the $1500-$2000 range, but what the hell - it's only money. Besides, I can't take it to the great beyond and I can always make more.
