Old school, but nothing compares!  Time owned: more than 12 months
This is an "old-school" device, before the days of digital... You tweak the knobs to get the sound where you like it; you're not at the mercy of some algorithm trying to tell you how it should sound.

Granted, it doesn't have the capabilities of some of the new digital filters - you can only notch out one interfering heterodyne at a time - but for day-in, day-out use, I prefer it. For vintage rigs, it is especially invaluable - makes it really easy to home in on a specific CW signal in a crowded band, for example.

It is extremely well made, a solid piece of equipment, and one you'll hang on to. If you come across one at a hamfest, grab it - if you're really lucky, the seller won't know what a gem it is, and you can get it cheap!

Great Improvement To SWL  Time owned: 0 to 3 months
Got mine on Ebay for $106.99 in 2011 in great shape worked out better then I thought it woulnd. Big differnce then the Radio Shack DSP filter I used for years! If you ever get a chance to buy one go for it its worth the $$$ to have. Makes my Yaesu FRG-100 sound a heck of lot better.
