is this place still in business there web site is under construction or does anyone have a catalog or anything

Last I spoke with them, they were selling the company to new owners. I think this was two years ago...

They got bought out by another company when they folded. No longer in business. The company that was currently selling the stuff stopped producing a number of items that RSM had developed, and the site is now even more useless than before.

There is/was a lawsuit against them for selling stock PCMs as "performance reprogrammed" PCMs for over $700. Around that time they changed their name, so if the business changed hands that's probably why.
