There is almost always the opportunity to buy second hand after a drop sells out. Only a small few don't come up or if they do are for ridiculous prices, Sunray for example. Most pedals trickle into the classifieds a week or so after people receive them, Lowtec took a while to appear, but was at a normal price. Of course Reverb is a good source as well, but prices are a little higher due to the tax/shipping/Reverb fees aspect.
I was on the fence about the Scorpion Deluxe, didn't buy it new, but picked it up in the classifieds not too long after release. This sales model seems to be working. Sure their could be fewer pedals always in stock, but I like the variety of pedals that come out, even if you don't get them new, there still is a good chance to buy from other sources, so long as you're paying attention to the classifieds.
I agree with nearly all of this. Things have definitely improved on this front in recent years as the drops have become more frequent.* My primary point is the lack of transparency around the time of release, the number of product available,** if the product in question will return in the future, and when that may be.
*I disagree that "only a small few" are difficult to obtain. Sunray, yes, but also Quicksilver, Mastering Equalizer, Bass Drop, big box PLL, Dream Crusher, Signal Cypher, Valve Champ, Modulation Station, Studio Boost, etc. Plus the Archive page does not list all past products. Not even close. You want a Sub Designer, Lazer Phazer, Archetype Valve Preamp pedal, Power Stage, or Amplitude? Good luck. But I don't have a problem with this because I know many of these designs were early or super-small batches and will not return, and that is fine. I get the Square Cheese and Tentacle II and ATD 12AX7 were one-offs and will not return. And I understand that the Signal Cypher and Broughctave are involved builds and also unlikely to return. Products are discontinued; this is the way of things. Again, my primary point concerns transparency around current and future releases (and re-releases).
**I am aware that one can check the number of units left if a batch has not sold out and, from that, derive an estimate of the batch size. I am also aware that no standard batch is smaller than 25 units and most are either 50 or 100 (though in practice they are smaller because early supporters and friends get first crack). I'm saying it would be helpful to have this information ahead of time.
I respectfully disagree. It is fun (to me). I take it as a game. I prefer it over the pre-order business model.
Yay, disagreement! My favorite

So much more interesting than talking to an echo chamber.
Alright, so I think it's a healthy to think of it as a game, though I will point out no other effects pedal company or product in my life operates this way. You can find it fun, but surely you can also admit it is nonstandard approach to business? I am not advocating for the pre-order model (though I do think that is superior) so much as more transparency around the current model. Consider how Doc Lloyd operates with batches of the DLA-2A:
Customers know when the item will be released, how many units will be available, and roughly when the next batch will arrive. Ditto for 3 Leaf Audio. For all of Spencer's shenanigans, in recent years he has done a decent job of letting customers know the time and size of a release and roughly when future releases will happen (aka if you miss this one there will be more chances). This allows customers to save up and plan. It also means they do not need to spam F5 for in indeterminate time; if a release happens in the middle of the night for someone, they can set an alarm and minimize the amount of lost sleep. Like, I'm already giving Josh my money. It would be nice if his model did not also require me to give him my time as well. This is why I think the move to built-to-order S300s is wonderful.
