I bought a used Hall of Fame 2 (through eBay) and a new Polara at the end of 2018.
They both seemed wonderful - until they didn't.
The honeymoon phase was particularly short-lived with the HoF2.
As I started upgrading my reverbs (first, with an Eventide Space and a Source Audio Ventris), the Polara, Hall of Fame 2, and also an EQD Afterneath v2 were removed from my primary board forever.
As others have mentioned, the Hall of Fame gave me that same brittle-feeling, cold, unconvincing reverb that couldn't compete with the two newer (and far more expensive) reverbs. I knew I'd never play that pedal again, once i played through those, so I sold it. Fortunately, I brought it used so I may have come close to breaking even on it.
The tone knob helped, some; but it didn't really warm up the reverb to my liking.
I also could not stand the 2-position pre-delay switch. If you're going to have a pre-delay option on a reverb pedal, it should be in a continuously adjustable knob; NOT a 2-position toggle switch!
Same with tremolo on an amp. Slow and fast settings, for an effect of this nature, make no sense to me, whatsoever. I actually never owned an amp that had tremolo built into it, but subsequently purchased nice pedals that did the trick, and have been very happy with those, since.
The shimmer algorithm on the HoF2 was horrid (to my ears), compared to that on other nicer reverbs. It sounded cheesy and contrived, to me. Night and day. I found it unusable.
The Polara was nice enough; but I didn't think it had anything, sound-wise, to write home about, compared to the others, which were clearly more serious units that were worth the extra cash. All the rave about the Lexicon algorithms seemed like hype to me, after really using it for a bit. I admit - they were nice. They just weren't fantastic.
Don't get me started on the artwork. Besides being fucking hideous (well....at least, to me), the color scheme made the knob labels extremely difficult to read.
I've never played through that pedal, since. It's been years,now. I should sell it, but I just can't seem to get around to it. It looks nearly new.
The Afterneath v2 gets very rare play. The v3 (that I also have) gets more usage, but I admit I'm spoiled for stereo reverbs, so others seem to get more love than it does.
I'm all on-board with the MXR M300 reverb as a (relatively) affordable, versatile pedal, for all that it offers. It's beautiful-sounding, and dead simple to dial in. Really usable algorithms, and all in a nicely-made compact pedal - in glorious stereo, with the use of TRS cables and a DIP switch change on the inside of the pedal. I've had that pedal since September of 2018. It's a keeper :-).
I've seen some,
used, on reverb, at a similar price point to what the OP was wanting to pay.
OP - sorry if I missed any post that mentioned what you ended up choosing, if anything. Did you find what you were looking for?
