I bought an Ultra RM years ago when the RFC members started posting good reports on them. The Leupold EFR's had always been my 3-9 rimfire scope of choice but I found that the Clearidge gave little away to the Leupold in the way of clarity or performance.
I've also bought four Ultra XP's in 6-20 - Two are mounted on Anschutz 1710 DHB's and I've found them to be excellent range scopes and very reliable.
I've bought quite a bit of other stuff from Jon at The Optic Zone and always found it a pleasure to deal with him.
