That "travel Time " is a great looking machine. I am not a Williams collector so I am not sure of the going rate for a Travel Time. it looks to be in great shape, very good BG, cabinet looks solid and bright. and if it is plug and play I would say he is not to far out of line with his pricing.
IMO any plug and play EM in better than average condition with a 8+ BG is worth a minimum of $500.00. in case you have not noticed the Supply of EM's coming up for sale of late is far out paced by the Demand for them. I have sold 3 machines in the last 4 months and have sold them for my asking price to the First person that came to look. Check Craig's List and see how few EM's there are for sale and if they do pop up how quickly they are gone.
You people that like to use MR. pinball and Boston pinball as a price Bible are Dreamers ! You can not find pins for the prices listed in those publications. you just cant. They are "Guides " but once again Supply and demand sets the market price.
IMO any plug and play EM is worth $500 + and a SS plug and play at least $700
Just my 2c
Good luck looking for your $300-400 plug and plays. let me know if you see any over the east side of the state.
