Make sure you get an
RLT pump and
not an RLXT pump (the RLXTs are for circulation pumps only and don't handle backpressure well). And yes, in the aquarium world they are a well respected brand.
You might want to shop around at a few more fish supply shops though.
the store formerly called The Pet Wharehouse has the same pump for $105
and
the place I have done most of my large supply buys for the last 15 years has them for $103
