That unit has been discontinued for quite some time. After that was the ALM 3220 which you can still find new, but then they launched the ALM 3222. This unit can do double or single sided (flush or sealed edge) while the 3310 is only single sided. When I used to be in digital press sales, I included a 3222 with a deal and the customer loved it, however, they tried to find laminate from other sources. The supplier indicated that it is proprietary, so I'm think it's the same for the 3310 (their brochures also call the lamination material "exclusive"). If you're looking for a lower cost unit than the 3220 or 3222, they also came out with the desktop version, 3230 which does double or single sided and it's around $10k. There are also other brands to consider like the Revo-T14.
