Im a remodeling contractor and just starting to dip my toe into the HF tool world for some larger power tools. Now that they are carrying some higher quality brands like Hercules and Fortress I am going to give some stuff a try (I run mostly Bosch tools). Is it worth it to get the extended warranties they offer? I picked up the 4 gal Fortress compressor today for $170.00 and they wanted $80.00 for a 2 year warranty. Are they ever worth getting? Pros? Cons?
