Best or biggest shop for 2nd hand mountain bikes please?

As the title  really. Only seen one so far, a small one on Theppraist Road, but they only sold new bikes.

 

any help appreciated.

which one did you check on thepprasit? there's also Ch.Numchai Thepprasit bike shop there, which has great reviews, but i'm not sure if/how many 2nd hand bikes they have. but they might be able to help. 
another option might be cadence cycle in soi jomtien 8. 

report back if you find something good. 

are you just looking for an option as cheap as possible for daily riding around town? or are you looking for a "real" mtb for offroad cycling?

Probably a hybrid just for getting about. Thanks for the recommendations
