Mankati?

I purchased a Mankati e180 about 4 months ago after reading glowing reviews about the printer. And it has been an excellent machine...no complaints.
I go online today to order more materials for it and a few spare parts and find that their website is down. Their "store" website is still running but you cant order anything and many of the links are broken.
Are they out of business?
Anyone know of good compatible 3rd party materials for the e180?

Thanks,

doesn't look good - getting a 'website expired' notice.
looks like it takes standard filament though - so that shouldn't be an issue.

Looks like the web site is working now.

I am only wondering, why in that price range did you go for this machine when you can also have a BCN3D Sigma?
