Gift Ideas for Investor Clients

[Jeff Dulla]

Probably the wrong category to post under but wanted to throw out a question. I have a decent amount of investor clients and repeat investor clients. For my owner occupied home buyers, I usually get a gift related to celebrating the excitement of their new home. For investors, I would like to do something different but I am blanking. 

Any ideas for a nice, investor/investment property related gift? Anyone seen anything interesting/cool? Don't know on budget but let's say $100 or less. 

Thanks in advance.
