Since there are about 5 large shrooms droping every day (some hof messages are hidden - remember this). This means there are about 150 large shrooms droping every month = 2 mod ek-2600 per month getting ingame (of course at start it may look slower cuz more people are crafting them adj->imp->mod rahter than one person collecting all but soon game will be swarmed with them).
Stats:
Adj fap: 21.67 h/sec, 25 eco
Mod Ek-2600: 48.60 h/sec, 25.71 eco
Curent price of large shroom is around 400ped per piece and price is rather falling than raising. One mod-2600 requires 75 of those shrooms and 140 dialy tokens (and ofc some regular ek-2600 but thats minimal cost). So atm you can get yourself this fap for around 30k-35k easily.
Since mod ek-2600 is more than twice better - there is no point that adj fap should be worth more than 15k atm and will be droping fast.
So i say tier 0 -
max 15k atm and soon 10k or less.
