I've been quite happy with the TrippLite equipment we've used in the past and I'm looking for good quality, reasonably priced racks to use in our commodity DC. One interesting one I came across was being sold by Dell alongside the Dell PowerEdge 4210 we use for the main USSHC DC - the TrippLite SR42UBEXP.
If anyone has any hands on experience with TrippLites racks/cabinets I'd be interested in hearing about it. I'm very happy with the PowerEdge racks but since I can find the TrippLites, which appear to be very comparable in design, for about 1/2 the price I'd be willing to consider them.

We have had one Tripplite rack come through our warehouse. I thought it was nice looking and well designed (although it seemed a bit flimsy during transport).
We still have a few new-in-the box Dell Poweredge 4210 racks available which may save you some money...
