I am in Canada and the cost of a Sandflee plus shipping in US$ was crazy.
I just bought a Flatmaster from Stockroom supply
http://stockroomsupply.ca/shop/drum-sanders.html Stockroom are in Canada and do ship to the US as they are very close to the border. They also go to a lot of shows in the US. Check their web site.
You have to buy and install your own motor. Which can be good or bad. I got one from Amazon for about $100.
The Flatmaster does not have the outboard attachment but that was not a big issue with me.
Setting up is a little time consuming but once set up it works well. They send you videos to follow.
I have only used a little bit but I had a large intarsia piece that I wanted to take down by 1/8 and it took a number of passes but it was right on. I also have used on a few boxes that I have cut off the lid and then it was not perfect as I did on the table saw. Few passes and a perfect fit.
Overall I am quite happy.
