I also suggest under 1k
Consider you need a PF ( 1000 ) ,  decals (200 ++)
So at 1k buy price , we would already be at 2200 bucks.
Add to that a hell of a lot of other parts for up top and I imagine under the playfield ( gotta be $600+ to replace plastics, posts, ramps etc etc PLUS any under parts) .......so now we are at a MINIMUM of 2800 bucks.

Add to all of that legs and a coin door plus 'hardware materials and time to fix the cabinet and your looking at EASY 3200+++ long term.

My Funhouse was frickin MINT , with all new everything and I sold it for $3300.00
$4500 is a LONG way off the mark 

And my apologies for my thread title IF anyone 'assumed' I was meaning the seller was having a go etc - at no time did I mean that , I just used a title to 'capture attention'
