Tubes for CJ EV-1 phono pre

My second set of tubes from CJ has finally expired, so I'm looking for suggestions and opinions on replacing the tubes for my CJ EV-1 phono pre. Tubes from CJ's stock sound just fine, but I'm not experienced at tube rolling, so should I order from CJ again as they recommend, or take a chance and seek else where? If you have tried tubes other then from CJ's stock on your CJ gear then please fill me in on your experience... I'd love to hear about it.
