I have done two or three bulk purchases of 150+ for my club and always through
Arrow.
Always try to order in multiples of 10 as a layer in a box of 100 holds 10.
Minimizes damaged cores in shipping.

Bulk order source for Ferrite beads?
I also recommend Arrow, both for cost and service, especially for small
quantity. It helps a lot that shipping is free for an order of $20 or
more -- IF it's a web order for what's in stock. I also got a very good
price on 100 pieces of the 2.4-in o.d. #31 toroids. Other good vendors
are Lodestone Pacific, Dexter Magnetics, and the usual industrial
electronics houses like Newark, Allied, Mouser, etc.
Note also that there is currently a tariff on these parts, which are
made in Fair-Rite's factory in China.
BUT -- #61 cores are NOT of much use for RFI suppression below UHF, and
they are a terrible choice for a common mode choke (often called a
"current balun").
