I'll also throw my lot in with Cyber. I know EXACTLY what it's like to try and make a living off of something you love doing while trying to help out others, only to get bashed in return for doing so.
I sell classic and modern videogames and accessories for a living, and everytime I post that I have items for sale on a classic message board, I used to get flamed for charging too much, or that I should be selling at cost to help everyone out, etc... etc...
Fact is, he's offering it for $100 less than what it's going to be priced, and $299 for what he's including is great (depending on shipping) and if I didn't have the tools, I would jump all over it. Even HAVING ALL of the tools I need, and ALL of the know-how, I'm STILL tempted to order one
When it comes down to it. How many of you would KILL to be able to build arcade cabinets for a living? Yeah, I thought so.
I'm not saying he's making a living off of this, I have no idea of his circumstances, I'm just trying to compare to my own. I'm sure it's a LOT more work than most people assume. Personally, I work over 45 hours a week on ebay and my website, and most people assume it's an easy 5-10 hour per week job.
