HP seems to make fine products, as does SMC.  SMC's 8624 for instance,
is widely used in clusters, also claims 48 Gbps, and sells for about $1000.
I saw a 48 or 50pt version at a tradeshow ~6 months ago, but I don't see
signs of it on the net...

offhand, I'd guess that even cheaper/smaller switches from no-name vendors
are not disasterous in performance any more, simply because all the vendors
probably use the same basic multi-port chips to implement their switches...
