Top one if you get 24V or 25V transformer (preferable), lower one if it's 48V or 50V. The capacitor needs to be 10000uF minimum, ideally a bit more so three of these in parallel is good (assuming you get transformer from Rapid, otherwise might be cheaper elsewhere, eBay, Farnell etc). This bridge rectifier is good as it wont need a heatsink. So about £60 in total...

If you got the bits posted to me I'd feel guilty charging more than a fiver to wire it up as it's less than 10 minutes work.

As Jazz just implied, you could use terminal block and crimp connectors instead of soldering.
