This is actually a tougher question than it used to be. There are a lot of books that have been dollar bin fodder for years but have started jumping up in price because they feature a first appearance or a character tied to movies or television.

I'd have said the first Micronauts series, but since the Hasbro movie idea was presented #1 has started to jump in value and #8 with the first appearance of Captain Universe has catapulted in demand and price. The Legends mini-series and Ostrander's Suicide Squad series are another example of what had been quality dollar bin fodder that is now suddenly in demand and garnering much higher prices. Others, such as the Wolfman/Perez Teen Titans are mostly dollar bin fare except for 2-3 key issues (you can usually find the entire run except for 1, 2 and 44 in dollar bins). And any run I recommend today might have a tv or movie option announced tomorrow and change it's status as dollar bin fare

That said, 10+ I would recommend as mostly dollar bin fare....

DC's Warlord (#1 and 1st issue Special #8 excepted, most of the rest of the 130 odd issues of the series can be found in dollar (and often quarter) bins if you look.

Ostrander/Mandrake Spectre series from the early 90s.

Doug Moench's Spectre series form the late 80s.

Mike Grell's Jon Sable Freelance

Max Alan Collins and Terry Beatty's Ms. Tree

large swaths of the Levitz Legion of Super-Heroes or any of the reboots if you are a Legion fan

Baron & Rude's Nexus

Matt Wagner's Madame Xanadu series from Vertigo

a large chunk of Kurt Busiek's Astro City can be found in dollar bins

large swaths of William Messner Loebs & Mark Waid's Flash runs

Grell's Green Arrow

The first one that pops into my mind, while not as well known, was a truly entertaining sci-fi title back in the 90's that I've recommended before :

Working through the A's you'd be wise to look for




                                                                                

Silly as it may sound, whenever I see the Deathlok limited series in a bargain bin, I buy extra copies. I just adore that series and have nostalgia for when those books were selling for ludicrous cash. So, I figure, at $1 a pop, why not buy another copy if it gives me a few minutes of warm nostalgia?

I'm surprised that Omega men #3 is not higher in price as it's the first appearance of Lobo.

Personally i think the days of finding long runs in the dollar bins is becoming a thing of the past. Most of the stores here in Phoenix hold onto their runs waiting for Free comic book day or special sales events for the 4th of July and Thanksgiving Black Friday and New Years eve where they run special $1-2 issues. All you find in the bins these days are the odds and ends from the last few years "events" which were over ordered and didn't sell. Two of the stores here actually have an "outlet" store of used comics separate from the main store (located in same complex but found in another store several doors down) with select days open to shop usually Fri/Sat/Sun only. 

There's a plethora of dollar bins (and even cheaper) where I live. In fact, my LCS has ten cent bins largely containing independent publisher output from the 80s and 90s. LOTS of great stuff to be found there. I bought most of my First and Eclipse comics that way.

About fifteen years back, a lot of LCSes adopted their sales strategy to acquire and unload massive lots of comics quickly, working off of larger number of sales instead of large profits per individual item sold. That model is gradually changing as back issue prices rise, but there's still a whole lot of worthless comics out there -- we're just seeing less of it from Marvel and DC.
