My Quest for an Arcade Cabinet

[TrakMastaTom]

Due to my room mate moving out, there is a room sitting in my home with nothing in it. I had this fantasy that I never thought could be a reality of putting an arcade cabinet in there, or maybe a pinball machine. I was checking out craigslist listings in Springfield, Kansas City and St. Louis when I ran across an ad for a Stargate (Defender 2) arcade cabinet in full working condition. The guy that wrote the ad says he would sell the thing for 500 or consider trading it for a Wii.

A Wii for a Defener 2 cabinet...what do you guys think?

Edit: Actually while I am at it, do any of you guys own arcade cabinets? If so, what did you pay and are you happy with them? I really want to buy one of those Neo Geo ones and get Metal Slug and Samurai Shodown, but I can't find any locally.
