This has been debated several times.
Spondoolies ("only") had around $4m in funding (before sp10).
Parts for sp30 production batches need to be ordered around 2 months in advance, chips more like 3.
Parts and manufacturing costs alone are around $2m per month (assuming 1000 units produced), and chip NRE is typically around $3-5M, which also needs to be gotten back.
Spondoolies already fronted the NRE, and cannot produce units without the parts (they in turn had to pre-pay and pre-order).
Sounds like mostly option number 1. Financing is hard to come by. But the other 2 are nice perks!
