here's one alternative...
SHIMANO CS-HG500 HYPERGLIDE 10 SPEED---11-34T MTB BICYCLE CASSETTE | eBay
SRAM and SunRace also have similar cassettes.
and if you went with an 11-32 cassette, there are literally dozens of choices, with all levels of quality... fit your budget to the quality level.... and yes, there IS a difference in quality of the metals, finish, and shifting as you step up a level or three!
changing to 11-32 will not require resizing your chain, btw...
