Cheap QR disc wheels

The commuter/training bikes rear wheel (Mavic Aksium) has died a death. Looking for a replacement pair as cheap as possible for a reliable wheel. Commute is 8 miles each way through London.

Have seen Shimano RS170 for £100, anyone used these? Would you go for these or stick with Aksiums, or what else is out there? Would prefer 6 bolt but everything appears to be centre lock now so not fussed in regards to that.

Thanks for any help.
