They do come up now and again. You've got to troll the exchange pretty hard tho. I've had bad timing scoring a Chopweiler, but I believe it will happen. It took three years to find a Mastiff when I had the funds to pull the trigger. If I had the scratch I'd be after that Desert Jack that's up. ETA: Whoops, WW was posting at the same time. Good suggestion to keep the choppy fund set aside. Just be careful not to dip into it when you see something else you want. I'd have had a Mastiff in my hands a lot sooner if I had followed my own advice, lol.
