I would be willing to pay more money to not have to piece it together..
That's usually how it works.
Craigslist, letgo, offerup, and as said KLOV and facebook groups.
I used to see them on CL pretty frequently, sometimes they'd come up 2 or 3 at a time. Always in varying degrees of desirability/completeness. But, it's been a while since I've seen any. not that I'm looking, but I keep an eye out anyway.
Long story short, be patient. Something will come your way.
Where are you located?
