Anyone that is 'sure' of getting $2000 for a 3/1 at Portland is living in cloud cuckoo land.
Diesels are not that popular in the USA, and although Lister engines generally have a good following, you'd need to be a bit gaga to pay silly money, even if it has been 'restored'.
Shipping is a problem, especially after the new regulations on pallet wood came in last September.
Payment is always a bit of a hassle with anyone who doesn't trade with PayPal or who doesn't use $$'s. We are over at Portland in August, be glad to meet up with any of the regulars if they make it to the show.
Western Union payments:
I have had two over the years, both difficult to sort out this end with our own banks, so these days I use PayPal for anything where possible. One payment never got cashed, our bank wanted more to handle the payment than the payment was worth, you live and learn.
5/1 and 6/1 engines in 'as found' condition should be available for £150 to £250 max. 3/1 engines are slightly rarer, but not exactly rocking horse sh*t either.
Sorry I haven't been around much myself, the factory move is nearly over and I'll have more free time then :-))
