Which would you recommend? The press kind seems to be a one shot deal. Life time usage on same cutter. No need to keep buying things over and over. Whereas with the drill kind...gotta buy circular saws (like nitrous, you gotta keep filling, er, buying...) and a need of a powerful drill. Although, the Dewalt cordless that I have cuts through 16gauge fairly easily, but thinking cordless.
