I play weird music and the Space Station is good and weird. A lot of the sounds are unique, others would be hard to imitate. Having to watch for the output level is a minor pain, compared to the range of new sounds the box offers.
I've been playing a long damned time, since before BBD's. I have a bunch of sick pedals, and a preference for mahogany planks with humbuckers. If my Space Station went FUBAR, I'd look for another one; there isn't anything else quite like it, and nothing to really compare it to.
I love the Tape Reverse and Ring Modulator effects. I don't really hate any of the presets, even though I'm not impressed with #9 Octabass. I wish it had stereo inputs, and an Output control; that's all I'd ask in the way of hardware. Other than that, copy the info off the bottom of the pedal and put it in the manual, too, that would help out a lot of users. I copied it all into a notebook, so I wouldn't have to flip the pedal over when I wanted to fool with a preset I hadn't used in a while.
The Space Station gives me an interesting set of effects to add tomy music, with only one or two compromises. I use it often, and I've even written pieces of music around sounds produced by the Space Station; that's pretty major.
One of my favorite tricks with the Space Station requires a looper, like the Line 6 Delay Modeler, or a long delay with a hold function, like the Boss DD-6. Put the delay/looper before the Space Station, so the Space Station tweaks your loops. Set the Space Station to #10 Forward/Stop/Reverse. Get a loop going, then slowly, push down on the Space Station's expresion pedal. You'll hear your loop slowly grind to a halt, then speed up in reverse. It's a lot of fun in a live setting, when people get that "How the hell does it do that?" look.
As much as I like the Space Station, this is a pedal you should really try before you buy it. I think most people will either love or hate the space Station. Control freaks who want MIDI and deep programming won't find it. Would-be pop stars who want a canned modern sound will probably hate the Space Station. This is a pedal for noise freaks, and fans of experimental/psychedlic/shoegazer guitar sounds. Add distortion and delay, and prepare to take off for deep space.
