I've got a 70m 10mm from Simond - no complaints at all. Middle is marked very clearly too. Got it in France for €100, August this year. Think its around the same in pounds in Decathlon here.
I've got this one: http://www.simond.com/fr/cat/Cordes/prd/Corde_Falaise_9mm
It's very hard wearing, hasn't gone black like all my Beal ones. Only down side is that I find it's not very stretchy - falls are much harder than with my Beals (Stinger and Joker). Personally I prefer climbing with the Beals.
In reply to THETWIG007: I've been using one as my indoor rope for the last 8 or 9 months, it kinks quite a lot but it's the hardest wearing rope i've had.
