...rather than necessarily the cheapest available.

I'm looking to buy a few stones in the near future, both natural and synthetic will be considered.

I have already ordered a DT 10x3x1" for £19 ($31) delivered
I have had a 4k Sun Tiger slip stone 4x2x½" donated to me

I am currently looking at the King 1k/6k combo, as this can be purchased for around £25 ($41), what are peoples thoughts on this?
Possibly looking at a PHIG as well, but not sure how different it will be to the DT?

What other options can you recommend to the budget minded honer?

Thanks in advance
