The reason I made the offer is so you could try it out and then you would have a whole year to decide but at least you are making a decision with knowledge. The track is expensive...new up to $7 per foot, used $4. The tracks, motors are not hard to find. The track, if you can not find them locally but there is a store in Novato, is on auction and so are the playmoibl/LGB motor blocks. I think the motors are around $60-ish right now, I only see those on auctions.
Also I have the plastic track as well if you want to try that?
I love excuses to go to SF as I like to take the kids to the museums, parks, events, church, and the overall experience of SF.
