Now that we know you're a rich Son of a gun, he he he! I'd say do the lift! The lift will be a very noticeable mod, which always brings a smile to my face!
P.S: I've been investing in Silver, it's been going up substancially for a few years now as well. The silver I invested in, has already increased 60% in value! I had to stop investing in Silver when I bought the house, but I've also been investing in Company matched shares for the past 7 years. When i put in $100.00, the Company gives me $25.00! I ended up using a large amount of it to use as a Down Payment for my house! Now that being said, I need to start buying more bullion and more Silver stock!
