This subject has come up a few times in the past, some people just don't GET IT when it comes to quality tools. You do have to pay extra these days (and in the past) to get something decent. That's why it costs more that the average brand. Why is it Sears, Costco, Sam's etc. are the main players here? Maybe it's all that advertising they brainwashed people with to convince the hoards that they are the only place to buy from.
I could be 100 miles away from the nearest retailer, I still would not buy from them if they did not carry a quality product, that's why it's EASIER now to shop the internet, research what's out there and so on. IR does make a good product, but I see that they make what appears to be different levels of a compressor, the sand colored ones & a silver series. I've owned a T-80 5 HP 80 gallon unit for 20 years, has held up great till just recently, motor blew out. But I wouldn't buy the sand colored version in the same size, they look (and cost) cheaper compared to what I have. There are other brands on the market that should do well to consider also, atlas-copco, Wayne, just as long as it is a cast-iron, oil-filled version with the minimum amout of CFM that you'll need. I would just start out doing searches on the internet with proper 'keywords' to see what distributors you can come across, some you may have to call for pricing & delivery options. But if your in a hurry, that will hurt you the most since you can't wait to find the better unit & price.
