Hi Jimbo,
I was on a fair this weekend and there were some alphabet trains to.
one train was +/- 3" high and cost $ 1,30 per carriage/letter.
one smaller +/- 1.5" high costs $ 0,70 per carriage/letter.
they both had wheels and axxes.
so looking at steve's train, I think that about $10 (depending on the length of the name) is a good price.
