Celestion DL6 replacement?

A mate has recently got on loan a pair of Celestion DL6 speakers and stands.
Not surprisingly, they sound rather a lot better than the little bookshelf
speakers he was using previously (if such things are quantifiable, the
improvement seems to me to be between 1 and 2 orders of magnitude).

He's already realised that, when the Celestions are returned (probably in a
few months), he'll find it very difficult to go back to the original
speakers and is consequently looking into possible replacements. Budget
isn't huge, maybe £100-150, and he's looking at stuff in Richer Sounds.

Allowing for Richer Sounds discount, is he likely to find something of
similar quality for that kind of money? For a similar spend, would it be
worthwhile considering DIY, and if so, what drivers would be up to the job?
(I suggested he take a look at Wilmslow Audio's site.)
