Sure, why not.
I have an NS-2 and it's now for sale. I'd take $60 for it.
Some guys like super-fast gates - mostly metal guys. Page Hamilton from Helmet uses a Drawmer gate, and it's a super fast, tight gate.
The NS-2 is not a fast gate. The threshold is easy enough to set, but even at its fastest decay setting, it's still kind of soft, both on the attack and the decay. By "soft" I mean its opening isn't instant and the close isn't either. The opening is fast enough for me - I'd say it's less than 20ms - but the closing isn't the tightest thing in the world. Maybe 50ms.
Some folks say the NS2 sucks tone because it's not true bypass. Um, I'm very sensitive to tone changes and I can say that I have cables that do more tone damage than this pedal. It has a buffered input (1Mohms), so even with passive pickups, it's not doing anything bad to your tone. It's the first pedal in my chain.
The Decimator is pretty much the same thing. The differentiating factor with the Decimator is that it uses some new technology based on time vector processing, which if you ask me is just marketing bullshit for computer processing. With a 500k ohm input impedance, it's not as buffered as the Boss, so you might wind up with a tiny loss of high end, but you won't notice it with that Tele of yours.
I'm of mixed opinion on that MXR Smart Gate. I don't like the fact that it's just an NS2 copy with an adjustable EQ circuit mixed in. At the same time, MXR has a habit of making great sounding pedals, so this may be another one of their genius moments. I would look closely at reviews of the pedal before buying. It's basically a downward expander attached to an EQ circuit - you can adjust which bands it's gating. I'm not sure that's flexible enough for me. Also, most noise in a guitar circuit starts at 60Hz (electric line hum) and develops harmonics from there that propgate through the entire amplified range of most amps, so I'm not sure how useful it is.
In my rack days I used to rock an old dbx gate, with a 160 soft-knee compressor. It sounded pretty good. The NS2 does about the same thing nowadays. Right now, I'm using the onboard gate in my Line6 AX2-212 for the goth band, and the onboard gate in my PodXTLive for a new project I'm working on.
