Comet here as well.
I was looking long and hard at a NEOS, a Gamma lockout, and the Stringway because of the foot thing and foot print, but they had a stupid Christmas sale on the Comet I couldn't ignore. I got a new one delivered to my door for €350 or so with a few tools thrown in. That was about 5 or 6 years ago now. During our short tennis season I string a few dozen racquets. During winter, I test strings if I get bored.
What I like:
Short throw, and short cranking. Loads of feedback when you make a pull. It is a fast, consistent machine. Requires very little lead string from the racquet to anchor a pull. Love the feel and action.
5 finger clamps that actually work very well and don't molest the strings.
Heavy, solid, simple build. Also, very solid. And it's also solid, yet simple.
Super reliable.
Still calibrates same as new.
The stringing platform is the perfect height. Just barely clears the puller, and it allows you to avoid ever going over the frame and pulling off of the frame to tension. It always allows a clear pull.
It has a table lock so you can do up a stupid, stupid, stupid Prince O-port if you are stupid enough to take one in to string.

Stupid. You wanna know why you failed, Prince? This is why.
Full height stand is available, and affordable.
ProsPro actually answer emails. At least they answered all mine before I purchased. Haven't needed to email them since.
What I don't like:
Guide rails and clamp design are a bit more grabby than they should be, so moving clamps can be a pain until they are worn in. They are chrome plated, so they take a while to wear in.
The clamp release can fight you on occasion. Just often enough for me to mention it here. They can be adjusted, tho.
Starting clamp not the best. Get a babolat. Still, tho, I can get away with the ProsPro clamp on 48# and lower string jobs. Not bad for a 5 year old clamp that came with the stringer. I still use it on occasion to clamp off if I am getting creative with a string job, or need to extend a string to anchor it in the puller...so long as it's below 48#...
When the crank stops at tension, the spring causes the entire mechanism to sing. You can silence it a bit, and I have, but it's always there a little bit still. It's fine now, but unsilenced, it really sings. You're not gonna do any late night stringing in a house full of sleeping family unless you have a basement.
Having said all that, this thing paid for itself before it saw it's second year of life. And, in all honesty, I rarely consider upgrading. Though I do love the look and feel of the Gamma lockouts.
I've used a couple of electronic stringers, and though they are a bit more compact, something about no feedback always bothers me. But I love countervail racquets? Crazy, no?!
