Well, my TMB 130 signature series refractor arrived last week (Thursday, May 15, 2008) after having been on order since late July, 2007. It would seem that it cannot reach focus without a diagonal mirror, and I do not own one, so I haven't had a chance to try it out yet. It looks great though.
I've got a MaxBright diagonal on order from Astro-Physics, so hopefully I'll get a chance to test it out when I get back from California in early June.
