Which stone for around 8k?

[rmihai]

Hi all,

I am looking for a 2 3/8" x 7" honing stone and I need your help - mainly I am thinking around 8000, but I am open to suggestions for between 6000-120000.
Important to me are, in order, keenness, maintenance, speed.
Money, as always are an issue, my budget is limited to US$160 EUR150 GBP110
To be honest, mainly I am leaning to towards one of these (in order):

Sigma Power Ceramic 8000 (or 10k, which has the advantage of a huge sharpening surface - 140mm wide)
MST Müller
Imperia La Roccia
Suehiro Gokumyo 10000
Arkansas Translucent

I am happily using for sharpening a 1000-2000-4000 sequence of Suzuki-Ya stones described here https://fabulalignarius.wordpress.com/tag/pm-v11-test/ which replaced a combination of Naniwa Chosera (sorry - too expensive their 10k) and Shapton Pro (which I MIGHT consider for their 8k or 12k).

Thank you for your help.
