I took a look yesterday and their site is indeed back up. I did see the .357 125 JHP's case prices are up noticeably from what I bought mine for a couple years back, but if I needed them I would certainly buy from MG again.
I remember back in '09 or so I ordered a case of the aforementioned during Christmas week on a Monday, and they were at my doorstep on Thursday. Extraordinary service.
