The one sancho linked is the boro plus the airflow pins. The one you linked above is the same as sanch's plus includes the air flow resteictor for the chimney. Compare the pics of the 2 items and you'll see what i mean.
Anyhow know how quick/slow 3avape are for deliveries? Tempted to get a preorder in
They are usually fairly decent even across the pond. BUT with the pandemic it's been fracking so slow...I placed an order on April fool's day and it's still in China according to the tracking info... That order was DHL shipped so as to expedite it.... No help at all....meh! I pre ordered the full set anyway knowing I'll not see either for a while....
