In my opinion they are cheap and the work i got done was amazing.
I got my profile cranks + chainring in Gloss Black & Bars stripped back ang done in Gloss White for $60. They didnt blast by bars they use a acid dip which is much much much less abrasive then just straight up htting it with the sand blaster. Which is a really good option for bike frames! The powdercoat is pretty thin aswell. If you ever saw that blue bike with silver fleck paintjob that erik sold a month ago, thats the stuff they can do.
Most places wanna hit you with minimum charge for each colour and even more for blasting.
Turn around time was a week, but they are pretty flat out in there warehouse. Well worth the wait though. My new bike will be done this wek soemtime so if you see me check out the cranks and see how well they came up! 
Cheers,
Gypsy.
