Agree your comparison is wrong. Pro with EL wire and led's is $4.7k vs $8.5k. All the other mods you mention could be added to either model and should be excluded from the comparison. Plus if you sold the pro, you could always remove said mods and keep them. To make choises more equal, I would suggest consider adding chrome mirror-plated hardware for $400, metal apron with cutouts for $150, playfield supports for $50 and few flashers thrown in. Now you have a better comparison and it would be $5.3k vs $8.5k.
