Used to own a couple of Mitchell 300's (many decades ago) and sold them to a friend to use for distance casting tournaments at the local Sportsman's Club. The Mitchell's I own/use now are the 308x's.

I do have several "old" reels that date back a few decades (not currently being used):

Diawa Procaster SM-2A baitcast reel
Shimano Bantam Mag baitcast reel
Johnson Jerk spincast reel
(2) Zebco Omega 171 spincast reels
Johnson Country Mile 10 spinning reel

And a couple baitcast reels that do see some use on the occasion of my yearly Birthday Night Bass Fishing trip :

Shimano Calcutta 200 baitcast (on my crankbait rod)
Quantum Energy E760PT baitcast reel (on my worm rod)
ABU Ambassadeur 2500C (backup reel)

First reel I ever owned & bought with my own money was a ABU Ambassadeur 5500C baitcast reel ($50) which was top of the line back in those days (early 1970's). Last "new" reels I've bought was the two Mitchell 308x's.
