You should be able to find most any Honda engine used for less than $1k shipped to your door with a 1 year warranty (except the B18C5, NSX motor, K20A, F20C - you know, performance-type motors). Depending on what motor you have, the core can be worth some money to people too. As long as it hasnt been oil starved or overheated, used motors can be great - I have put them in several vehicles.
