I'm not sure what happened to the PN version. I looked at Oreck's web site, and the standard version is still there, at a ridiculous price of $299.99. I found the Douglas version selling for $89.99. Doing the math, the Oreck is 3.3 times as expensive.
Back to the original posts, I'm interested in the metros. They are still around, and produce hand vacs that are similar to those found here, along with a full size metal canister line. I'm wondering if anyone here actually owns one of the modern metros, and has any impressions. I'd also be interested to know how the history of the older models. As one of the last true metal vacuum holdouts, building a machine externally similar to what you could find on the market 50 or 60 years ago, I figured collectors would have taken greater interest in the brand. At the moment I can't think of any collectors that I know who owns one.
