I was in this same boat about 7 years ago. I'm sure I don't have to tell you, but if you piece it out you will get much, much more money. Probably double. I took my time selling my Playstation stuff and got over $20k just from that. Then I just wanted rid of it and started selling in large lots and I regret doing it that way.
You know what it's like selling 50+ boxed systems all at once? I do. It still makes me shudder when I think of how much I sold it for.
I'm treading carefully, I checked the value of every game I'm selling and I've priced my lot accordingly. I simply don't have the time to list that many games individually.
Yeah, I have 4 consoles for sale right now and that's bad enough trying to get those tested/listed/shipped/etc.
I understand completely. I was working 50+ hours a week and spending 2-3 hours a day listing stuff on ebay.
I did have pretty good success selling on nintendoage.com and gametz.com too. People generally pay a bit less on forums, but without all of the ebay fees and non paying bidders it was a bit more profitable, for both time and money.
