I don't think those 1 grand estimates are taking into account your requested assumptions (i.e. no PC, no monitor, etc...)
ok, so take $150 off for my monitor.
rampy, have you built one up from scratch?
Parts needed:
wood
screws
brackets
paint
primer
controls (joysticks, buttons, trackball, spinner, interfaces)
coin door (this is optional but makes it look authentic)
speakers
light
marquee
plexi
bezel
replacement bits for all the broken or dulled drill bits
I'd say the controls,interfaces, and wood are what takes up most of the cost.. plus I have parts that I bought that are yet on my cabinet, like ls-30s, dual strike twistygrip yoke, etc...
Plus how is a monitor not going to be included in the prioce, you plan on playing by sound? $150 for a 20" trinitron 2 years ago was a killer price
It all really depends on how much you want to put on it and into it.
You probably could build a basic, non-original cabinet for about $500 without any bling bling.
