Hmm, a little tough, but doable. Your criteria I believe are:
$60 or less, lightweight, low-riding, & good steel.
"Good" steel is subjective, but I'd say anything 440C or better would fit that criteria considering the relatively low price point. I would not get a SOG Flash I, BTW, it's just too small. Having said that, I'd recommend one of the Bokers. Personally, I like the Trance for the $, but it's AUS 8 (I don't mind it, but it might not fit your idea of "good" steel), so I'd suggest the Hyper or M-Type, depending on the size you want. Both knives have 440C, lightweight, are low-riding, & are well under your budget.
If you don't mind some of the handle showing, I think the B/M mini or full size Grips are great for the $ & you can probably pick either size up in the F/S section of the Forum. They're lightweight & with 154CM, they definitely have "good" steel. You can always have STR make you a low-rider clip down the road (I happen to have an extra one for my Strider PT & it fits the Grip, so I know for a fact they work great).
Good luck.
