Dave,

I was able to get a quote for you, Iris from Redsail said:

Dear Lee,

Very glad to speak with you.

50W laser tube is USD180/pcs, DHL shipping cost to the door is USD196. So total cost is USD376.

Please feel free to contact me for any questions.

Looking forward to hearing from you.
It may also be worth looking on Aliexpress for a new tube: https://www.aliexpress.com/w/wholesa...-tube-60w.html
