There are some good deals. Not on the same scale as the Off Road Expo because there are less vendors- but you also have a lot more face time to negotiate. ARB (locker) and G2 (gears) are listed. G2 is a 4 WHeel parts brand so you have a good chance. I bought my G2s thru Rebel Off Road though- might be worth a call before you go so you have a price in mind. RWKHause Auto
has good parts pricing too.
