Are all Boro Beads and similar items at the listed CL for availability?

[JamesWTGames]

Alright, so I swear I’ve seen things on this before, but I cannot seem to bloody find them atm. But I think this is a limit of the aonprd more than anything. But are all lvls of Boro Beads all CL16? I thought I remembered seeing that each lv had a CL equivalent to what lv you needed to be to make the corresponding extract so:
Boro Bead VI -> CL16
Boro Bead V -> CL13
Boro Bead IV -> CL10
Boro Bead III -> CL7
Boro Bead II -> CL4
Boro Bead I -> CL1

I technically have the same question for Pearls of Power and similar. But the reason I’m asking is that my DM is being very particular over specific rules, but very open on others, (we’re using Elephant in the Room reducing feat taxes for example). And we’re in Iron Gods, and starting in Torch for the entirety of the first module, we’re lv2 halfway to lv3. Which has a listed population of 4,320 which is slightly below the size for a ‘small city’ and thus he’s saying ‘major items’ cannot be for sale here. Even though I can't seem to find things defining what a 'minor, medium, or major' item is. Our group is currently hard pressed for items to improve ourselves, and this is by far the single best thing either myself or the Magus could buy with the 1,333 gp we got for rescuing Khonnir Baine.

I feel like I’m forgetting to mention something here… but not sure what…

1) Boro beads should follow the same principle as the Pearls of power, the one explained in this FAQ.

Note the Boro bads requirements:
Requirements Craft Wondrous Item, creator must be able to prepare extracts of the extract level to be recalled; Cost 500 gp (1st), 2,000 gp (2nd), 4,500 gp (3rd), 8,000 gp (4th), 12,500 gp (5th), 18,000 gp (6th)

That is what matters.

2) What area Minor, Medium, and Major magic items is determined by the Random Magic Item Generation tables, table 15.2 and following in the CRB.

To make an example, the table for Armor and Shields: Table 15-3: Armor and Shields.
+1 and +2 armor and shields are Minor items.
The tables for the other books aren't available on AoN.

Boro Beadsare in Ultimate Equipment, level 1 e 2 Boro Beads are minor items.

3) There is the "Base value" for the community too. Barring modifiers, a Large Town has a base value of 2,000 gp.

Quote:

Each community has a base value associated with it (see Table 15–1). There is a 75% chance that any item of that value or lower can be found for sale with little effort in that community.

In theory, you have a 75% chance to be able to find a level 1 Boro Bead or Pearl of power.

Thank you Diego! I sent my DM a link to this, hopefully that alleviates some of the confusion. So in essence lv 1 & 2 Boro Beads according to this are minor items, lv 3 & 4 are medium, and lv 5 & 6 are major items more or less from your explanation and the chart on armor.

I know there's other useful stuff to buy early on (our party has a major carrying capacity issue for example), but given how I'm somehow a ranged character with the highest potential full and touch AC in the party not using all 3 of my lv1 slots to prepare 'shield' I feel is a worthy investment.
