I have one of the older SOG SEAL 2000 knives, adopted by the Navy for use by SEAL teams after very grueling tests. It has a very wide tang under the synthetic handle.
This and the Swedish Fallkniven knives are the only ones I know of to have passed especially tough govt. tests. A couple of the Fallkniven models are approved for unit purchase for use by US air crews. They have govt. stock numbers. Another (A -1) passed tests, but is too large for the sheath on US survival vests.
I've examined several of SOG's other models & they are well made and well finished. I don't like the swaybacked blade shape, but the knives seem to be very high quality. The handles of some are too short to take the Fairbairn-recommended grasp. The SEAL 2000 is better in that regard and is a very rugged knife. They have re-designed it and I don't like the looks of the new one.
I'd buy Fallkniven over SOG (or Cold Steel), but that's largely personal preference.
I have never seen a folder by them, but the sheath knives are good. At the price cited, I suspect that the knife is made in Taiwan or some other Oriental country. But my smallest Gerber Applegate-Fairbairn folder was made in Taiwan and is a very good knife, especially for the price.
Is this something with the typical SOG swaybacked blade? That'd turn me off, but some like it. You might price the U-2 folder from Fallkniven from US dealers. I have one and it is a fantastic knife of its sort. Small, but very strong, sharp and efficient. Mine was a gift from a Swede, so I don't know the US price, but you should check. Dealer prices here vary. Shop around.
I don't know why you want this knife, but if it's for defense, look at the Gerber Applegate-Fairbairn folders. I wear them at home and other private places. I'm a little concerned that some cop might deem them a "dagger, dirk, poignard, or stiletto" so usually carry a Benchmade Model 710 or a Puma lockblade that closely resembles the Buck Model 110 when in public. My Gerber blades weren't especially sharp as made, and I had a custom knifemaker hone them.
My general use pocketknives are mostly Victorinox Swiss Army models. I wear the lockbacks in a discreet belt pouch.
Is there a good warranty on this SOG item? If it looks good and seems solid, I suspect that it's a good value, if you like the looks. What are the materials for the blade and the handle? At that price, I'd expect 420 steel, but it's not as bad as some say. For most real world use if you aren't cutting carpet or such things a lot, you'll probably like it. Buck uses a 420 variant, but they have a very sophisticated heat treating process that gets the best out of that steel. I don't know what heat treating SOG may use.
If you like the looks and the knife feels good in your hand, you can't lose much at that price! In general, SOG has a good reputation. NOTE: I have not seen the new SOG's from China. What I said is based on their older knives.
My only assisted opener is a Kershaw. Nice knife, but I don't carry assisted openers. It stays on a bookcase near my front door.
