BN,
Based on what you want a small knife to do, I recommend the new Swamp Rat Hairy Carry.
Some good pics by Jeff in his Rainwalker Kydex sheath:
It is not INFI. It is 154CM. But, it is a GREAT design and 154CM is a very good quality stainless steel with good edge properties that is more than sufficient (for most people) for a smaller EDC type blade. It can be had for $138.95 - Well below your max price. And you can pre-Order it now.

Search Swamp Rat forums for some more pics recently posted by some people just starting to receive shipments.

The Scrap Yard Mud Puppy should be available soon at a reasonable price of $89.95.

Again, not INFI. But, a great design. Many people LOVE mudder grip handles. But, some don't and prefer micarta. But, the Mud Puppy is basically an AD blade shape on a Mudder style handle for a LOT less. Again, 154CM should be great steel for a smaller EDC blade.
If you insist on INFI for a smaller EDC, I like the Scrap Yard SS4. The SS4 is a Res-C mudder handled version of the Meaner, but with a functional choil. The SS4 sales for about $200 or so on the Bladeforums exchange. (sometimes....)
The Swamp Rat HRLM is an awesome knife and blade IMO. It is SR-101 which is a very good knife steel. Search the Swamp Forum for a lot of pics and reviews.
The AD is my favorite Busse/INFI small blade, but I personally don't like the non-functioning choil/Talon Hole combos on these smaller blades (fine with me for 5.5" + blades or so.).
Many others love the AD, Meaner and Game Warden and don't seem to mind the Talon Hole/choil combo.
The Game Warden's handle doesn't fit my hand quite right, but the AD and Meaner handles are excellent :thumbup: :thumbup: (... except for the Talon Hole/Choil issue.

....... Again, some people don't mind...

)
The ABA (Anorexic Badger Attack) from a few years ago is very nice if you can find one. They aren't cheap IMO. But, the HRLM is a very good alternative at a much better price.
**** Right now, you might consider waiting for the Busse SAR4 and the MiniMuk.

:thumbup: There have been some proto pics of the MiniMuk posted, but I don't know if that will be the final design. I don't think any pics of the SAR4 have been posted. I am anxious to see what it might look like.
Good luck.
