A co-worker has offered to sell me a brand new un-used, still in unopened box Dillon 550b that an old girl friend bought him. His selling price is $250. I'm considering buying it but don't know squat about reloading or reloaders. I would most likely only be reloading one caliber and that would be 9mm since I burn through so much of it at the range. I already have countless thousands of once fired brass so the cost savings is there and the pay back on the press shouldn't take long. I guess my question is, are Dillon's any good? Was the price offered to me good?
