When researching kit, it can be a bit of a minefield establishing what you want, which brands/manufacturers to go for, and then actually finding a supply route.
Whilst TLA does not endorse any particular supplier without due cause/experience, we have curated a non-exhaustive list for easier reference and purchase. Listed in no particular order.
