Rhino does make good hardware.
Another local vendor is Xorcom; while their parent company is based in Israel XorcomUSA is based in Phoenix.
The only thing I like about Xorcom hardware over Rhino is that it scales a little easier.  It is USB2 based so you don't have to worry about whether the motherboard is compatible with PCI cards (3v/5v), you can fit a lot of telephony hardware in a small amount of space (for example this install: http://picasaweb.google.com/twingeckos/FortPolkJointReadinessTrainingCenter#), and it generally comes out at a slightly lower price for the customer (sometimes significantly less).  
That said... I don't care for the XR1000 server that Xorcom sells as it is too underpowered to expand (ok for demos) but the XR2000 and XR3000 servers are fine; they will be coming out with a more powerful XR1000 soon thankfully.  

Sangoma also makes fine Asterisk telephony hardware.  I haven't tried any of the Chinese Digium knockoffs and probably never will.  I don't recommend mixing different vendor's Asterisk telephony hardware as it is very un-likely that the combination has been tested by either vendor.  
For 'roll your own' servers I recommend Server Micro hardware.

Since the phones are what users actually touch get good phones :)  For phones I generally prefer Polycom or Aastra phones.  You can use Cisco phones if you flash them with the SIP firmware (there is chan_skinny for Asterisk but why complicate matters); you may have to set qualify=no to avoid registration issues.

Could anyone recommend a consultant or firm that provides Asterisk based phone system support / installation? Thanks.

 

I would love the flexibility of having a Linux based PBX, but if I need some local resources who have worked extensively with Asterisk based systems to reach out to when I get stumped by an issue.
