I like the variety MSC has and suspect that we will be limited to certain pages or a certain budget for materials.
The only problem is that for those of us in the West there are only two offices, both of which are about a 10 hour drive from LA. That means that unlike many teams in the East, we MUST use their shipping department. Hopefully it will be better organized than SPI's. If I request overnight shipment, it had better be here before I can drive to Reno and back. Assuming I make their deadline for same day ship of course. On the other hand, if I'm that desperate maybe there are other problems too.
Personally I would have prefered Mcmaster-Carr, but this isn't too bad. If they're as big as McMaster then they won't have any problems handling our piddly little orders.
The enhanced sensor capabilities are good news too. I think I'll go borrow the Procurement guy's Banner catalog and go drool a bit. Then I'll go figure out how to get them working on EDUbot.
