The absolute cheapest barrel I would buy is the Group Buy Monster logo barrel which are currently being manufactured by Green Mountain. Any rack grade barrel is luck of the draw just because of the manufacturing variations. Some cutters are more worn when your barrel is manufactured and variations in the actual barrel steel.
I think people put to much expectation on cheap barrel accuracy. High quality barrels are more accurate with a wide variety of ammunition and normally shoot good with little to no break in. Button rifled barrels like Lilja, Criterion, Shilen get good reviews as do Wilson Combat and Noveseke. These barrels cost more but in the long run might prove financially cheaper if you want batter than average accuracy.
Accuracy for me requires a good trigger and I really like the LaRue Tactical MTB 2S on sale for $87.
