Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

I loaned my 5 year old Husqvarna 136 chainsaw to one of my area managers at work as he had just moved into town from Michigan, and need to cut down a few trees.  He had the saw for a while and admitted to abusing it a bit, but stated he would pay for the damage he did to it.  I took it to a local dealer in Chardon, Ohio and their quote to fix the saw was $10 less than what it costs new.  My wife feels that this guy owes me the entire amount necessary to fix or replace the saw;  I said that since it's a mechanical object with a certain lifespan, that I would be kind and take the depreciation on it and only ask for around $100 to put towards a new saw.

Am I being too easy on this guy, or should I make him pay for 100% of the repair/replacement cost?  I can see my wife's point, why should I have to pay any money when I started the entire interaction with a completely good chainsaw.

Thanks
