And, if you don't already (and I may just be stating the obvious) check the topic board DAILY and post what you want/need/just can't live without in the Wanted and Wishing section.
I've purchased 2 of the 3 Alembic's I own and both an SF-2 and F1-X in that fashion (as a lot of others also have done). In all cases people contacted me to let me know they were interested in selling something i wanted (my 6-String 96 Europa) or saw that someone else was selling an item in which I was interested (An SC Signature Deluxe - Thanks again Jazzyvee).
The regulars here set fair prices, are great with providing honest descriptions of their gear, and at least in some cases, have a heck of a lot more musical gear to sell that they have accumulated over the years than I will ever own.
