Sonic Foam System - Plier & Tool Set - 7 Pieces - 1/3 (Small) Subtype - Air Compressors Prevost Non-Scratch Blow Gun: TheseThese are the tools I've decided to use at OGHQ, they have a nice quality to them with good ergonomics. They aren't intended to replace everything but there is a great variety of tools offered here. For the price, you cannot beat them vs something that's 2x or 3x the cost like Snap On.
