Opinion on Sequence pumps

[Ronfire]

Thinking of the sequence 4000 series 5000 gph pump or for $20 more get the 5800 model.
Anyone use these? how quiet? best place to buy? Any advise is appreciated.
Heading to AZ from BC Canada for the winter and thinking of purchasing the pond equipment I need while there.
Thanks.

Sequence is an old, established company respected for the quality of their external pumps.

I like sequence, have two, they are quiet, easy on the electric bill.

I have 7 Sequence Pumps running 24/7/365 and very quiet. Longevity is great too. My newest has been running 6 years while my oldest has been running 13 years.
