In reply to Boulderdash86:
If you're looking to limit costs get a Fly as others have suggested, rather than another Cirque as this will allow you to then upgrade to a full pair of tech tools later more cheaply. Also, not sure they do a Cirque hammer (a hammer likely to be handy sooner or later).
Or if you've got a bit more money, consider whether you want to get a matched pair now and what you want those to be (Flys, Quarks, Reactor etc etc). This would avoid having a redundant Fly hammer or two cirques if at some point in the not too distant future you find yourself plumping for a more technical set.
