The low buck sim cockpit.

http://www.gteye.com.au/product/gtey...gitech-g25-g27 $70 (although I understand spring rates so I could probably scavenge something cheaper)

Lumber, paint etc. $100
Now relatively speaking that may not seem low buck but we're talking a decent quality full force feedback experience that's only missing actuators to move the seat for $637 vs 2k for a decent FF simulator seat without any other gear.
