Neil, after spending the last 18 months or so working in the US, where i used the Unisaw on a couple of occasions, i have to say that IMHO you have got a good deal.
Why? If we start with the cost then a Woodford Xcalibur 806 clone with the optional arbour extension and dado set would cost you around £1419.95 (including the 21% VAT in Ireland and delivery), which is around £300 cheaper than the Unisaw, but if you count the £166.98 of extras you got with your saw then the £133 price difference is not very much at all, especially when you think that you have got a original Normster and not a copy. 8)
It may not have a sliding table, but neither does the Xcaliber as standard, and if you want to buy one for the 806, it will send the cost up to £1870. And lets face it, if the Woodford is a exact clone of the Unisaw and you really want a sliding table in the future, then the one for the 806 may fit.
One thing that i had noticed about the hobby woodworker in the US is that a lot of them use sleds instead of sliding tables.
As others have said, I do not think that you can compare the Delta to the Scheppach, but one thing that i have found with my 2500 (old style) is because the mitre slots are non standard you cannot buy and use out of the box accossories such as the Osborne EB3 mitre gauge, a lot of Incra products, and even tenoning jigs. If you want to use any of these you have to adapt them. On the other hand it seems that they make every sort of accessory for the Unisaw.
I do not know if the new Scheppachs have the same problem?
All in all i do not think there is anything wrong with importing the Unisaw, even if it does cost a few hundred more and because of the great distance, it is going to be a hassle if anything wrong.
As far as i can most New Yankee Workshop lovers want a Unisaw because Norm uses one, and it is because of this that it now has its clones.
The most important part of buying this table saw is that Neil wanted one, and if he gets the emense please out of using the saw as i did when i used one on the other side of the pond, then i am sure he will find that it is worth every penny.
Good luck with your new toy Neil, but don't grow a beard and wear plaid shirts :norm:
Cheers
