Any US dealers w/ 450Gs and 493AHs in stock? My regular supplier has been backordered for some time… Im down to my last 450G and need supplies! PM me!
This board doesn’t support PM’s.
Give Mike or Josh at TenX Networks a call (1-801-746-4140). They’re a MikroTik reseller (or distributor). I recently purchased an RB450G from them, and I believe they have more in stock.
Be sure to tell them I referred you. 
www.wlan1.com has them.
