Your right, that kind of stuff can get a little pricey.
I have a suggestion.It's not as elaborate or as fancy looking but would solve the problem for way less money.
You can construct a u shape piece which would mount inside the cabinet.
Use 1x4 for the top piece. Extend each side down approx 2 inches. This is where you will attach one section of a drawer slide.
Cut a piece to proper size,attach drawer slides. This will be your slide out section.
You can mount hooks on the bottom of the sliding section to hang pots.
Hope this helps
