You don't need to get in a high price bidding war over an automatic fly reel, and certain models remain essentially unchanged for years and years; they might be relatively new production but look just as "Vintage" as essentially the same manufacturer's reel from years ago. Martins are reliable and easy to come by new or lightly used, and I never saw one yet I wanted bad enough to pay more than $25 for. I have Martins, but I wouldn't tout them over something else. Just do some Ebay searching and grab what suits your fancy as you won't have much money in it anyway.
Perrine and Pflueger come to mind as other grand old names in auto reels, but there are many others. Possibly you'd want to match the reel and rod brand, as somebody suggested in another post just recently.come to think of it, get four or five, and mount some reel seat brackets on your truck bumper so you don't need a winch if you get stuck or want to pull your boat back on your trailer. Really, auto reels are a heck of a lot of fun, especially on heavier 'glass rods for panfishing or bass fishing, which is more or less their traditional use. Plus you can pick your color scheme from gaudy to conservative.
