We got a used DC250 about 6 months ago, and have to say it is an excellent machine. We got it to replace an OKI C9650 which we had from new, and had nothing but problems with in the 6 months we had it. It was so bad, we got the dealer to take it back and end our contract. The OKI was sold to us as a real production machine, but in reality it is not. Colours are all over the place, colour registration was terrible, drums only last a fraction of their life and the service was a joke. I think the OKI has a place in offices, and maybe in P4P for banners and the like, but it is no good for day to day running.
I am in the UK, so not sure how prices compare, but we paid £9,000 for our refurbished DC250 with bustled rip and professional finisher. After running the OKI for 6 months, the DC250 has been a breath of fresh air. It has not been without its teething problems, but now we are getting to know how to run the machine, I am very happy with it. One of our customers is a print broker, and he keeps asking us how we get such amazing results from a 250. Things we have picked up are when running 130gsm gloss coated, you get a better print if you run on plain paper setting as opposed to coated. Also, when running business cards 21up on SRA3, the sheet to sheet registration was terrible, but running them 10up on SRA4 the registration is excellent. I know that means double the clicks, but the result really is good, and business cards are usually only in small quantities anyway. We only have the standard bypass feeder on our machine, which has minimal problems with skewing. We had the tech fit an uprated side guide kit to ours which keeps the guides in position and has virtually eliminated any skew problems we did have.
I would recommend getting a DC240/250 as long as the price is right on both the machine and the clicks. Having the machine on site so we can do jobs on tight turnarounds has helped us win business with many local companies.
