In your price range I would definitely have to point you towards the core lineups from both spyderco and benchmade. Given the fact that you want to keep the blade length under 3", spyderco's, with their finger choil are going to offer the best ergos and most grip in this size range. Benchmade offers the spectacular axis lock. Both companies offer several options in your price range with the advantage going to spyderco with more models. Pick one you like the looks of and go with it.
In terms of spyderco you're looking at the delica 4 (most prefer the ffg version), caly 3, native 5, and the sage series under 3" and within your price range. I personally think the best value of the bunch is the sage 1, which features excellent ergonomics and cutting performance and carbon fiber scales and s30v blade steel for around $100. The sage series is made by the Taichung Taiwan factory which produces arguably spyderco's best knives, featuring fit and finish normally only seen in knives costing several times more. Don't worry about the fact that it's made in Taiwan, Taiwan isn't China and the folks in Taichung are world class knife makers.
In terms of benchmade, the mini griptilian is the standard. It can be found around $ 60 and is an excellent edc choice. 154cm is easy to sharpen and holds an edge reasonably well, and the noryl gtx handles, while cheap feeling, are actually very tough and durable and make a very practical choice. The standard models are also available with either a drop point blade and thumb stud or with a hollow ground sheep's foot blade and a thumb hole. There is an upgraded mini grip called the Doug Ritter mini RSK 1 (ritter mini grip) which features a different blade shape which makes it a better slicer at the expense of the pointier tip as well as upgraded s30v blade steel. The Ritter grips are a bit more expensive at around $110. The mini presidio and presidio ultra also fit the bill. The presidio features aluminum scales and 154cm blade steel and the ultra is the budget friendly version that takes a hit in materials. The bone collectors are another option and are basically g10 sheep's foot presidios with d2 blade steel. The only knock on the presidios is that they are quite thick and bulky and are known to shred pockets.
There are many other choices out there, including pretty much all of Kershaw's catalog, my suggestions are just the beginning. Best of luck in your search.
