flirt poles are easy..... $15 for everything at lowes or home depot.
10ft pvd pipe, rope, and a bite surface...
thread the rope throught the pvc pipe, tie a knot at the bottom, and another knot at top (leave about a foot of slack so the rope will move around a bit) and then tie a bite surface to the front end and BAM! flirt pole!
spring pole is a little more work.. im building mine as we speak haha
