A good all around inexpensive envelope filter

So, the question is simple and so direct that I couldn’t find an answer on previous threads:

What would be TB’s suggestion for an inexpensive no frills good all around envelope filter? Just something that could work in a function band to get in the ballpark of top 40s covers. Doesn’t need to be perfect.
I'd recommend the EHX Nano Q-Tron here for a no frills cheap plug and play mu-tron sounding envelope filter. Super easy to dial in using LP mode and the volume control can ensure no boost to your volume when you engage it. For a slightly higher budget, then I'd suggest the MXR BEF. That's a bandpass envelope filter but the ability to blend in your clean signal is a great feature, and, whilst it is up sweep only too like the Q-Tron, there's a bit more variety to the range of sounds you can get out of the MXR.
 
Envelope filters are really finicky, they react different to every bass, touch, and technique. If I'm a player who plays super light on a passive bass, and you are digging in really hard on an active bass with every control cranked up to 11, my recommendation for a good filter is literally useless because it will never sound the same for you as it does for me.

I've been hunting for a new one for my board and trying out lots of models, nothing beats plugging multiple pedals in side-by-side and A/Bing them with your own instrument. If that's not an option you might look to Amazon or other online vendors that have an easy return policy, because you just won't know how a given pedal is going to react in your hands until you can plug it in yourself.
 
MXR is a band pass with a blend. EH nano Q is low pass or band pass or high pass with drive/level And EQ center. And a little cheaper unless you get a used MXR.
I use the EH in either low pass or bandpass (like the old DrQ.) I use the eq difference too. With enough level (1 pm) the low pass on it's lowest eq is basically what I'm looking for in an envelope, not a quack. Influenced by Bootsy using the old giant Moog...or Bill Lazwell and his customized DOD. Another modern good'n is Walrus Audio Kangra.
But come to think of it, in a function band the function of the MXR quack might function better.

What kind of top 40 covers are you doing?

I went around and around on this and ended up with a Future Impact for 80s tunes. It either nails or gets super close to the synth sounds from that era.

As for new envelope filter pedals, I use a super cheap DOD Fx25b or a not-so-cheap Maxon filter.

A compressor after the DOD is key to tame the massive low sweep that wants to shred your speakers.
It gets a classic quack though and the blend helps keep the bass from getting totally lost in the mix.

An added plus is the super cool dub sound from the DOD when the sensitivity is set to never open.
