You might consider the ramifications of these sales. Neither EBay nor Sheriff sales are conducive to pre-buy inspections.
I bought a seized B-90 King-Air out of Mexico once and re-furbed it for skydiving. Could have bought a rather nice one here in the States for less when the thick, white smoke cleared. Be careful, there is usually a good reason the airplane is being sold the way that it is.
Unless you have experience buying and selling airplanes through the more traditional sources, you run a high risk of an unpleasant experience.
Best of Luck.
