I bought one of those turning tools of John, not bad for the price he is selling them at!

The other thing to try is find a local second hand machine tool dealer, I called in at one in Leicester a couple of weeks ago and he had box's full of second hand tools and tips, after hunting round for half an hour I came away with a indexable tip turning tool, an iscar indexable 3mm part off blade with holder, 2 nearly full box's of tips for both and a nearly complete 58 piece clamp set for my router.
Grand total - £35 - Bargain, a box of tips would be more than that.
