I like Pass. cars. Have a few sets. However, I do not have any Seaboard units. Searching the net I found the above two listed. The images are very poor and details are also poor. My question to you please, if anyone has these sets or have has had the opportunity to view these sets I would like the benefit of your opinion. Is their any major differences between the two set units, also your personal preference between the set units. Thanks for your time and input. My best regards. tommy
