I am the same ... I do not keep or take receipts from my LHS. No point. As for set ups let's se how cheap it can get:
SC 46 engine: USD55.00
Phoenix Scanner: USD75.00
Extra Electronic 4 ch: USD120.00
Tuned pipe: USD50.00
Hand pump: USD10.00
No need for electric starter and other nice stuff ... still my best plane to have fun with
