pump info for a friend

[sea gnome]

My friend is starting up his 55 g tank and needs a pump for both a protien skimmer and a return pump. I think some of you use one external pump for both with a t connection and control valves. Money is a concern and jl has a quiet one on for $165. Would this be powerful enough and a good choice or do any of you have any other suggsestions? He will probably begin setting it up this month.
