I think you should look at either the Boker Rescom or the Spyderco Remote Release 2. The RR2 is designed for the type of application you specified and can be had for around $50. http://spyderco.com/catalog/details.php?product=205
Lockbacks are the best for accidental opening prevention as they have a design that resists opening and actively closes the blade up until a certain point.
A fully serrated Spyderco with a pocket clip is also a great choice as Spyderco makes some of the best serrations in the business. You can usually find excellent deals on slightly used to used knives in the buy/sell forums here.
