maplins do a decent drill at a very reasonable price, then you can get the accessory set too, I have bought the mains drill, accessories, and the smaller 18v mini grinder set, branded everise, probably totalling about half your budget, they work very well, though 2 things I havent yet got are a drill stand / drill press, and a flexible drive shaft. (the only downside was the collet that was in the drill when it arrived was out of true, all the rest were perfect so it may just have been there for transport / testing)
