Absolutely I've heard of them... Good? For sure!!!
They were around years ago and they've recent come-back these past couple years... However, they've seemed to have eluded me.
Their website
http://www.ocassoc.com has been up for a couple years but there's only that first page... NEVER have seen ANY change.
I got an email from them not too long after that website went up, since on RAP, I was expressing general interest as I was doing some preliminary research on all the options out there because I was soon to be in the market for a new compressor.
If I recall correctly, I remember emailing them back to let them know I was interesred and when more information and pricing became available, to please let me know; as at that time, they we're just getting on their feet.
Unfortunately, they never did get back to me... I just assumed they never did get the ball fulling rolling since the site never changed from the first-time I had seen it!
I never did bother to try and email them again though... Figuring it's probably way out of my price-league anyhow.
If they ARE available, I don't have any money for one right now, but it'd sure be goal of mine to save for one!
Oh... So much gear and so little dough...
