If I was "in your shoes" and if you have the space instead of buying one higher prices machine I would pick up two or three cheaper machines. High on my list of those "cheaper machines" would be Space Shuttle (backglass looks great with machine off so something to look at when not in use) a fun machine that looks great, Pin-Bot (good value yet and fun to play), and if you have the room for a third pretty much any other Williams System 11 machine.
It never made sense to me to buy one $7500 to $10,000 machine if you have room for 3 "cheaper machines". But everyone needs to do what is best for themself.
