I use Acer too. I have both laptop and a desktop X3810 (space saver), both work well. Look at the specifications, get as good a spec. as you can for what you can afford. You shouldn't need to pay more than the equivalent of £400. If you are limited in finance then see what PC World have in refurbished laptops. Staples often do demo models cheap (my x3810 was one, £235 without the monitor).
