Replicator Accuracy

Can someone tell me how accurate the replicator 1 is/was compared to the replicator 2 and thing o magic?

I have an original cupcake cmc and it was not very accurate when building technical parts with holes in them. especially smaller parts it got way off up to 1mm.
I am looking into upgrading to something new and will mainly be using it for mechanical parts prototyping.

Thanks.

Well i know that the Zotrax and Ultimaker 2 are very accurate for there price,

I would recommend them above any replicator product as price and quality goes.
