As tigerstyle says, it does depends what you're using the drills for. If my previous recommendation is too pricey, may I also suggest the set I used before the Erbauer one - http://www.screwfix.com/p/titan-ttp508ki...tid=187470 - A less powerful set, but still saw me right for almost 2 years before the batteries started to fail. 10% off at the moment too. 
Only downside to them is the drill doesn't have a hammer setting.
