Audio Lathe was bought out about 2 or more years ago by 1uptechnologies ... just checked that and it is now 1upmultimedia.com/dubplate.html
I used to use Audio Lathe as an alternative to Vinylcarvers - they were cheap, quick and good - $20 for a double sided 7"
Unfortunately 1uptechnologies are very expensive - $37 plus insane shipping rates - and of course the TOTAL value PLUS shipping will get declared on the customs.
I ended up paying about £95 total including customs charges for 2 x 7" acetates. Both were OK in quality, but they took so long to do them, and send them - plus customs delay, all in about 8 weeks.
In fairness, the exchange rate was $1.40 something so it wouldn't be quite as expensive now in UK terms, but i bet it would be about £80 for 2 acetates
Don't go there.
