Hmmm fair enuff, but i used to churn out 'A' birch cabs with blank 'A/A' playfields for around $100 and sell for $150, and that was 2-3 yrs ago, prices for wood and fitting didnt jump that much.
If you don't mind me asking, what were you paying for wood sheets? I've shopped around a fair bit, and at current pricing there is more than $150 worth of material - and that's before you even switch on the CNC machine!
