The Boss Space Echo emulation pedal (RE-20) is not bad. I found one 2nd-hand for $150CAD.
I also use a real spring reverb from an old Traynor P.A. head and run the output into a DI box before the mixer. The combination of saturation and verb I get from it is very nice! A buddy that I do live sets with loves it so much that he insists on dragging it out to gigs
