John,
I extol the virtues of Chester machines all the time, purely for the backup service you can get from them.
If you are on the lookout for a large benchtop mill (as the century is), unless you are already committed to MT3 tooling, then I would look at a machine that has an R8 quill. It really is so much better than MT3 and you can get just as much tooling now as you can for MT3 and at the same price. The Century is a bit of an unknown model, and that should be taken into acount when it comes the time to buy third party fitments. They are either not available or only obtainable as full price accessories from the original supplier.
I know a few people that have gone for the Seig X3 and it's variations (including the latest version, at a higher price) and they have all been delighted with their purchase, once the obligatory strip down, clean and adjust has been carried out..
I am not saying don't buy the Century, as it looks a very capable machine. Just look at others in that price range, as you can get a lot more useable and desireable features for the same sort of money. Plus the spares backup for a popular machine will be much better, and most probably cheaper, should you ever need it.
