My advice would be to stay away from brands such as Mercury, Intex, etc. They simply do not match up to the likes of Altec, Logitech, or Creative. Also, no point in getting a 4.1 set. Either you get 2.1 or 5.1; but on a tight budget, it's better to invest in a good 2.1 set rather than in a cheap 5.1 solution. I don't know about the specific model you mentioned; but I'm sure it will be a decent set.
