NMR Probes

I am going to purchase a H,C,X triple resonance Z-gradient inverse probe
for our Bruker 500 MHz spectrometer. I have been looking at both Bruker
and Nalorac probes. Typically in the past, I would just go ahead and buy
a Bruker probe. I believe the Bruker probes are robust and easy to use.
Furthermore, I have not had many problems with most of my Bruker probes,
which makes the decision even more difficult. For the specific probe
that I am considering, I find that the Nalorac S/N spec and pricing is
somewhat better than Bruker's. However, I have a better comfort zone
with the Bruker probes since I have never used a Nalorac probe or had to
deal with Nalorac as an organization.

I guess what I would like to know is what are the experiences of others
that have used both Bruker and Nalorac probes, and what do they feel are
the pros and cons of a Bruker probe or a Nalorac probe. Additional
unknowns to me about Nalorac are things such as service, availabilty of
loaner probes, turnaround time for repairs, how do Nalorac personnel
work with you when you have a problem, etc. I know that I am looking at
a fairly new probe design, but I would like to get any replies that
discuss these issues or specifics about the pros and cons of this probe.

If there are many replies, I will consolidate them and e-mail them back.

Regards,
Kurt
