Got this one off Amazon for under $60 which is great value.
Cassette seems well made and machining looks good. Cogs are rivetted on the spiders nice and tight, so should be rattle free.
Weight is a pretty respectable 386g, helped out no-doubt by the 40t ring being made of aluminium.
Cogs are as follows:
Sunrace 9 speed wide cassettes
Sunrace are also doing a couple of 9 speed wide range cassettes (11-40t). The CSM980 and the CSM990; It's so good to see some manufacturers stepping up and providing us with the wide range cassettes in 9 speed that Shimano and SRAM have refused to make.
