Home Made DIY Jigsaw Table With Blade Guide for Under £30

I bought a Wolfcraft Table from Amazon and because a blade guide wasn't available I built an arm with bearings to attach to the Wolfcraft Table.  The parts used to make the arm were salvaged from an old steel bed-frame and the bearings were taken from roller boot wheels.  The current version doesn't have a safety power off switch but otherwise it works well and cost £0 (not inc Wolfcraft table at around £25.)
