Excalibur EX-16
From the Reddit /r/scrollsaw subreddit:

"Excalibur scroll saws are highly regarded in the woodworking community for their unique tilting-head design (rather than a tilting table), which allows your workpiece to remain perfectly flat on the table while making angled cuts."

21" Pegas
From Bear Woods Supply:

"Upgrade your scroll saw to the incomparable 21" Pegas Scroll Saw, which features the game-changing blade clamps, and enhancements from our Swiss engineers to improve the saw and reduce vibrations. While it’s made in the same factory in Taiwan where the Excalibur scroll saw used to be made, Pegas has added Swiss precision and engineering to their scroll saw. Let’s start with a beefed up chassis featuring a reinforced web in the connecting rod and vertical rocker and needle bearings pressed into the rocker arm as opposed to a sleeve and bolt connection that is prone to wear and failure"

RBI Hawk
The RBI Hawk has been discontinued since the RBI went out of business on 2006, though owners are enthusiastic about using them. Here is the Google A.I. Overview:

"Long revered as professional-grade tools, RBI Hawk scroll saws are celebrated by woodworkers for their exceptional smoothness, heavy-duty build quality, and lack of vibration. Users consistently praise their raw power and reliable tensioning, though potential buyers should be cautious about parts availability since the original manufacturer went out of business"

Wen 16 in. Variable Speed
From Steve Good's Website:

"If you are looking to upgrade from an entry-level saw this can be a good choice. The WEN is not the same quality as some of the high-end saws but is less than half the price. The value is good because this saw runs pretty well. Watch my review if you want to see it in more detail. Is is a large step up from any of the entry-level saws."

Velocipede
OK, we only use this one at the San Diego County Fair, but it is an interesting machine, nonetheless. Here is the Google nA.I. Overview of it, though we take exception on the "quiet" part. 

A velocipede scroll saw is a rare, antique, pedal-powered machine introduced in 1876 by the W.F. & John Barnes Company. Users and antique restoration enthusiasts praise the saw’s unique bicycle-style pedaling and tractor seat, which offer a smooth, quiet, and dead-point-free cutting experience without the need for electricity.
