That same station sells under several brands. It's about as good as it gets for $20 but I wouldn't buy from Circuit Specialists because by the time you add shipping it's significantly (by % at least) more expensive than buying off eBay, although eBay currently has a promo running to take 10% of $25+ with code PTAKE10NOW (expires April 6th) if you wanted something more expensive.
On eBay one of the more popular brands of that is a Yihua 936B which can be had for about $21 delivered. Despite some sellers claiming 60W, they are closer to 50W. The recovery (reheating after each joint) time is a little slow, the temperature a little imprecise, and the wand cord is fragile and a little shorter than I'd like, but that's about all you can expect for a $20 station.
Besides price one thing in its favor is that it takes the same (900M series) tips as the Hakko 936 so there are both good quality genuine Hakko, and cheap lower quality clone tips readily available. I would get genuine Hakko tips for at least the one or two tip shapes you like most. In other words you'll probably seldom want to use the included thin conical tip.
