What are some online CNC machine shops that you guys like to use? I found one called First Cut (Proto Labs). One project/quote gave me a big sticker shock (oh well... it's a complicated piece/design). Another project/quote was reasonable (after seeing the first quote, everything else becomes reasonable ha ha).

Are there any other similar online CNC machine shops that I should try? Best if they can do threaded holes. Typically will use strong aluminum alloy material. Great if they can powder coat it too. Small prototype qty only. Preferably located in the US but if they're overseas they need to be really low cost, high quality and fast:)

Thanks
