As someone who lives in HK I would say you were looking at Knockoffs.
None of the real MP's you mentioned have been retailing for prices that low...
MP-21 is always $350+, Streak and Prowl are low $400's..., Lambor varies from mid $300's up...
Did they have the ST markings and holograms on them?
I only deal in real but might head over to take a nosey next week as I'm curious to see so I can be wary...
Always nice to be able to compare the real to the fake. I have a real and fake MP-10 that causes (non-collecting) peoples minds to blow when I put them side by side. 80% think the fake is the real deal.
