unabe to develop PCB - positive photoresist

[moffy]

It makes no sense to talk about prices. JLCPCB wins that hands-down.
Important is the difference from computer screen to solder: 1.5h vs 1.5 weeks.

The price of the JLCPCB is excellent but it is the delivery charge that makes it more expensive than home PCB prototyping, plus the time as you mention, but for the final product it's hard to beat.
