The $16 one isn't just as good. That's a non-ratcheting tool. It's hard to get the right amount of crimping pressure with those. I don't recommend going that way. The ones in the $30 range are better. $29 with ten pairs of connectors thrown in looks like a deal. Another option that I found in a Google search is to buy the PowerPole die (the ham companies sell them separately for $25 and they're a bit cheaper on eBay) and combine it with a cheap crimp tool from Harbor Freight - total cost $30-35 but that doesn't include any connectors.
