Cassette for 10 speed shimano

[vejnemojnen]

I was wondering, whether there would be an option for 13-25 10speed shimano cassette, apart from cs-6600 ultegra.

Is there a less costy way for getting the desired ratio? I'm not rigid about 13-25, I only need to have the 14-15-16-17-18-19 cluster. 13-23 would be even better, because I sometimes find the 2t jump between 19 and 21t annoying.

thank you for your input, advise

I know, but I was hoping for a cheaper option.

WHy there is no tiagra-level 10spd cassette with 13 or 14t starter cog?
