Tripp Lite Racks - Any good?

Can anyone tell me if they've had good or bad experiences with Tripp Lite racks? This looked like a nice price for a 4 post (with free shipping):

I have two of these in my garage - They work great.

You may want to check craigslist/backpage for a rack though....waaaaaay cheaper!

Yea, I just bought 4 APC 3100, nearly brand new for 325 each on craigslist.

Sigh.. Very jealous. I've been looking constantly on craigslist and ebay but there's nothing available in my area. I may just hold out and keep looking on those sites for a better deal than paying retail. I'm not looking forward to all of the costs to order in all of the different rack mounts/shelves I'll need anyways.
