I bought one...works great!
Yeah, but for how long? There's a reason why they're cheap. It's because they're cheap....
And of course there's bound to be a half-way decent one out of all the crappy ones, but why take a chance getting one that's mediocre at best when you can spend a little more for a known good one that'll be better? Do it ONCE and be done with it because you get what you pay for. Most people try and cheap out to save a few bucks and it usually ends up costing them more in the end. Don't buy cheap Chinese garbage and things usually work out much better.
