many of these being sold these days don't have the touch screen on them... If they dont', you can pick them up on ebay for less I think.... (take a quick search... shipping is the issue)
But if it DOES have the touchscreen... think about how fun it would be to play missile command with a touchscreen!
Also, always consider going with a SVid TV instead. Cheaper if you want bigger, and MUCH better output for arcade games... Goto Oscars site about his right up to see what I'm talking about.... It really does a better job for arcade games... new 27" would be about 50 -100 bucks more then what your talking about with shipping... and you have a warranty...
