I am going to buy a new return and closed loop pump.I would like to know what pumps are good and what pumps are bad ?

Can I buy the same type for my return and closed loop or should they be a different type.

I thought the Mag Drive was the way to go but I have seen a few post here that say they are nosiy and run hot ?

Last but not least I am on a budget and would like to keep the cost down but want a releiable pump in other words if I don't need a Dart then I don't want to buy one but will if that is the right pump.

Thanks
