A budget ESC will get you so far.....lets say that one or someday, you get much better at your driving skills and or you just want ot go faster. A budget ESC will hinder that in a huge way. Assume you spend 60-70 bucks on a decent ESC, then you get bored with your current setup and decide to upgrade for....say....Top of the line. Well, you're already out 70 bucks! Seriouesly, a really nice ESC will save you hastle and money in the long run.
Just my opinion though.
