Chod

Here, here! on those little Bosch Drills. I've got the impactor, drill, the right angle driver, and 4 or 5 spare batteries. I like the brand and batteries so much that I recently bought the Multi-Max 12V. Bought it fora specific job and since then have used in regularly. Great control and a very versatile tool for make fine accurate cuts in difficult locations.

Only down side is that the batteries really don't like the cold. I've got 4 12 volt units with bags that I have to take out of the van every night or they'll be dead.

As the saying goes, "imitation is the highest form of flattery." I doubt we can find too many craftsman in any medium who do not have a pile of magazines/books related to their craft. What are these resources for? Sometimes copying an item helps improve our craft and along the way we may discover something to improve upon.
It depends on the kind of person you are. Some love the work and some love the money. If you don't want to be copied, don't put your work out there for all to see.
