It appears that some suppliers are listing the Dart Gold as discontinued??
The problem with Reeflo pumps is that they are notorious for break downs. I used two darts on my previous tank, one on the closed loop and the other on the return. The closed loop pump was fine the entire time I owned it, other than being a little noisy and requiring significant maintenance I never had a problem with it. However the return pump was replaced 3 times due to the seal leaking and causing the bearing to fail. The first pump only lasted a couple months from new. A quick search will show I'm not the only one with such problems, many owners have gone through this. In fact it was such a common issue Reeflo now requires you to handle all warranty issues through the manufacturer because all there distributors got sick of dealing with them.
The other problem I see with the Gold series is the price, over $400 for the Dart. Sorry but I can't see it being worth that much. A RD doesn't cost that much more in comparison and will actually last. There are no seals to fail, uses less power, better bearings, better shaft and impeller, much quieter and it's got the reputation to back it all up. I would honestly bet you'll need at least 2 darts to match the reliability and lifespan of an RD, that easily puts them at the same price. Remember you'll need a back up pump if you use a reeflo
