Hi,
I fully agree with Frank on this, if you like it and can afford it get it!
BUT and this is a big BUT, if you are thinking of buying to sell on you need to be very carefull as chinese weights (and I use this as a generic term for mass produced weights that are bought by the crate load) tend not to resell well or make a big profit in the second hand market.
If you want to collect and maybe sell the odd weight then get what you like!
Kind regards,
KarelM
