Define cheap. My AeroMax (wings and tail feathers completed) now needs the fuselage kit. $8k (AUD) That's not expensive, except that the entire Ranger can be built for less than half that amount. I looked into building the Airbike - Wings $2500, Airframe $6999 (USD). The Legal Eagle is $3000 - $5000 ($4500 - $6500) - and you need to be able to weld. Even the Affordaplane is about $3000 USD ($4500 AUD) and you need to source 6061-T6 AL tube (which can't be had in Aussie for love or money). The Ranger (like the Aeromax) is almost completely CNC cut, and uses plywood. But the Ranger costs about a third of the price. For me it's a no-brainer.
