Second set looks like genuine Aisan releases.. tho I'd be very concerned about them getting thru customs. A lot of UK sellers say their stuff is in the UK but it comes direct from Aisa and gets stopped.
I would steer clear of the first set. the box is of season 4 only.. a common trait when listing dodgy goods. length of auction and BIN looks like priced to sell quick
compare these to the complete set on amazon and you should see the differences your looking for... :P
