This seems to be a good price on a lazy tong (accordion) style riveter. They're not as compact as the pliers-style riveters and will need more space to use, but they put less strain on your hands and require less effort. I couldn't find an RRP, but it sells for $107 at Tool Kit Depot. Lazy tong riveters typically cost more than pliers-style riveters within a given brand. It seems to be well-made and has a smooth action.
A riveting deal =)
