Go Outdoors are currently doing a Beal Karma 40m for £45, I bought the 30m version 5 years ago and it's still going strong after indoor & sport use. Not dry treated though if that's an issue.
+1 for the Beal Karma..... just bought the 60m for £57 & it's doing well in the Dolomites. Tempted to get another & chop into 35/25m sections for cragging & toproping the grandchildren in the Peak
