I too was trying to save money on mine. This is what I have used pretty hard for 500 hours, works great for me.

90599 TOP LINK CYL CAT 1, 20-28" 1
18653 3/4"ADJ. ORB X 1/2"FEM. PT hyd fitting x 2
86668 1/2" X 24" HYDRAULIC HOSE x 2
86641 1/2-14 NPTF QUICK COUPLER W/BALL VALVE MALE 8GPM x 2
It was $215 shipped for me and have been worth every penny.
Hydraulic side link is from "CWA" on amazon. This is the description:
2 1/2" Bore x 4" Stroke x 1 1/2" Rod, 3000 PSI, SAE 8 Port Weld Clevis Cylinder
I did have to cut one side off the cylinder and one side off my factory side link and weld them together. But for less than $100 it was a no brainer. This setup has held up for me. YMMV.
