Two great source of cuttings are Jon's cutting offer (usually in February) and UCD cutting offer (requests are due by Nov 01, but there has been some question if they will continue). Between the two there are many extremely good varieties available for not a whole lot of money. There's no reason to settle for crap, here.
In the mean time, you may want to find a live plant you can grow while you practice with cuttings. You'll be a couple of years ahead of the game in terms of getting your own fruit. Check out Jon's Availability List for trees. It is probably dated, but it's worth checking into. Others in similar zones to you seem to have good luck with Chicago Hardy, Atreano, Marseilles Black, and Voilette de Bordeaux. There are many members of this forum who are growing in similar zones who have done some of the leg work in selecting for you including, but by no means limited to, Herman2, Drivewayfarmer, 7Deuce, Bass, and Gorgi.
