Also, I'd just like to add this little bit of wisdom...
Don't EVER assume that prices will drop or remain the same and put off getting something that you really want because you think or especially because others tell you that you'll definitely get a better deal later on.
Years ago, I really wanted a Walther PPK/S, but had noticed that they were getting harder to find and that prices were steadily increasing across the board. So I asked folks if I should get one immediately or wait. Of course, all the folks who already had one of their own told me to wait because sooner or later prices would go back down and I could get one far cheaper. Eventually, I got tired of waiting and bought one for a price that I was comfortable spending. Everyone told me that I had wasted my money because they were totally going to plummet in price. Guess what, they never plummeted in price, in fact now they cost a good $250 more than the "terrible" price I paid back in 2016.
It's easy for folks who already own something to tell those who don't to wait for something that they want, then ridicule them for paying more than they would for something they already bought when prices were lower, but they don't end up having to pay more when prices go up.
So yeah, if $140 seems fair to you, then buy it. Don't bank on prices going down on something that's rare, out of production, and prices have evidently already gone up on.
