I ordered this one

I like the push button release on the clasp, and thought it makes it look like a much nicer watch

Your band is cracking because part of the strap is overlapping the plastic tab. I've had a cheap Ritche band on mine for almost a year without taking particularly good care of it and with no sign of cracking, because the way it attaches avoids stress on the plastic. You don't need SteelConnects specifically for this.
