Warning: The following is not financial advice. But you know how it is.
I have waxed at great length in the past about the Böker G-10 balisong "large" model 06EX228 and also the tactical balisong "small" model 06EX227. The latter of which being, in my not-so-humble opinion, one of the best value (and better built) EDC sized balisongs available, bar none.
Well, previously available. Because back with that post we determined via what BladeHQ told me these were discontinued. And it came to pass, there was much wailing and gnashing of teeth.
Well, I just discovered that all four of Böker's spring latch balisongs are currently available and marked down on their web site. Heavily.
06EX229 Tactical "Large" (Ball bearing pivots, spring latch, D2), @ $40: https://www.bokerusa.com/balisong-tactical-big-d2-06ex229
06EX227 Tactical "Small" (Same as above, but EDC size), @ $36: https://www.bokerusa.com/balisong-tactical-small-d2-06ex227
06EX228 G-10 "Large" (Regular pivots, spring latch, D2), @ $40: https://www.bokerusa.com/balisong-g10-large-d2-06ex228
06EX226 G-10 "Small" (same as above but EDC size), @ $36: https://www.bokerusa.com/balisong-g10-small-d2-06ex226
As usual (and despite my best efforts) I have no affiliation with Böker whatsoever so I don't gain anything if you buy one of these or if you don't. But if you're into this sort of thing I would consider giving any of the above a serious look. Get them while they exist... I am positive these are still in the midst of phase-out.
The "Tactical" models in particular (the 06EX229 and 227) are an appealing alternative to anyone who's been wishing they could get their hands on a Benchmade model 32 or 51, especially given that they are similar sizes and made of the same steel, have the same kind of spring latch, and have ball bearing pivots.
Side note: At least one variant of the Papillon is also on sale, but alas the Papillon is kind of crap. I would give that one a miss if I were you unless you were truly desperate. Its trainer variant is also available but it's kind of a raw deal that it's not on sale, so the live version is actually significantly cheaper.
