I suggest you make a list of the features important to you. Then see which models match up. Then check out user reviews at Amazon and Newegg. Finally, do comparison shopping. Ebay has a lot of clunkers, but also some very good deals. The hard part is dividing between them. I know - I refurbish laptops and sell on ebay. If you buy used, the seller's rep is going to be very important.
As far as Acer v. HP v. Asus, etc - all the makes have some clunkers, but most of their stuff is very good. Dell may be more uneven than HP, for instance, but Dell has put out some really great units too. They all have strengths and weaknesses that vary by model and unit.
