I've got a like new sm122 milwalkee ph monitor and jbj reg with bubble counter. the reg has some tarnish (brass w/saltwater u get the idea). I'd do 125 bucks for the combo. The tarnish does not effect performance just looks. I had it on my reactor but am now using a milwaulkee reg (off my planted tank).
Also comes with a solenoid.
LMK!
Cheers,
Kurt
