I know a lot of people recommend a DMT 325 for lapping honing stones, but they're pretty expensive in the UK - I see them for less than $50 in the US, but the cheapest I've seen here is £60 (> $90). Getting one from a US supplier is not an option, as USPS postage is extremely expensive (about the same price again as the stone).

So I'm wondering if anyone has used EZE-LAP stones, and whether they're any good? The 8x3 ones here are more reasonably priced (and postage from Germany to the UK is cheap).
