I 've tried cutting corners, in the past, when it comes to the boat stuff. It's just not worth it. Learned my lessons long ago, go with the stuff that has been tested and proven to work. You'll find them to be the better choice and the better value. You might spend more up front, but you'll get many years of service out of them, that to me is a better value. (And you get all of the advantages that sailingdog mentioned.)
This is true for all related marine purchases, it does not pay to cut corners and go cheap, you'll pay more in the long run.
