I agree. I had that Olympus, and it was amazingly good for the low price. A cheap Porro or reverse Porro for $100 is sometimes better than a $500 roof. The $100 Leupold Yosemite 8x30 will beat most roofs up to $500.I bought an Olympus 7x21 PC Classic reverse porro from Amazon years ago for only 30-35 bucks and it was great. I got rid of it when I had to start wearing glasses. I wouldn't buy a cheap roof, but the cheap porros and reverse porros can be quite good.
