for standard mounts, you've got the Renault parts; pattern parts from suppliers like ECP/GSF/etc; Kangoo diesel mounts (which may or may not be stiffer than the Clio's - still don't know!)
'uprated' mounts; you've got the Powerflex poly dogbone bushes; the Vibratechnics mounts that KTEC sell; or the Group N set from RenaultSport (which are prohibitively expensive for most)
you'd pay twice as much for a set of uprated mounts as you would a set of standard mounts; they'll add noise/vibration (not unbearable imo - subjective), but will be stiffer than the OE set-up and should last considerably longer as well
