We are also in the acrylic business with 3 laser machines.
If you want a powerful Laser tube you can choose from GSI a 200W tube.
1. EZCUT from Taiwan it's very, very good, we have one since 6 years working very well.
2. GNLASER from China it's also a good producer but you have to say what do you want the machine to be built with.
3. JINAN WISDOM MACHINERY - don't buy from them, very bad producer and and also not honest people.
You also have to make a small study and see if it's economical to pay much more for a laser tube of 200W if 80% of your business it's based on 2mm up to 5mm (my case).
I also have a SYNRAD F200, it's maybe one of the best lasers in the market, but only the price of the sealed laser it's enough to buy 2 Chinese laser machines.
