The Red Sea Reefers that seem to be the biggest problem is the 750. To be honest it's their size and stand that might be their Achilles heal. If you are looking at a smaller size Red Sea is a good tank.
Keep in mind that these ones with leaking pipes are all older tanks and the Orings are easy to change. Orings should be changed anytime the unit is disassembled anyway. If assembled correctly from new they should last a very long time. Also if for some reason you develop a leaking Oring from the pipes it drips straight into the sump. No water will get outside of where it should.
It's your call. But if I was buying a smaller tank Red Sea would be on my shopping list as well as a few others.
