Do you own a laser that has lasted working fine?

Hi there, been reading and finding many testimonials having mixed experiences on commercial laser engraving products (laser modules I mean), after a bit of research it seems like a quality problem, some are happy, some are not: because some lasers just died without any reason (no heatsink problem, no driver problem, etc). I'm looking for a new replacement, for my custom made CNC engraver.

So this is that time when more than technical help, a brand or quality testimonial is needed. Yes my commercial violet laser died despite all the correct and appropriate cautions after a few sessions of 30 seconds each one. There it is, I will appreciate testimonials on what has lasted for you. Tech research on amazon testimonials is taking too long despite most of them not being quite specific.

Thanks in advance.

Need background? here it is, been working with lasers and engraving, built my own laser CNC engraving, and several of my laser burners with their own power driver, etc, so at this point perhaps I'm not a newbie. But I'm about to buy one, preferably violet laser 500mw+ for burning. Yes I know about specs, I just would like and welcome any feedback on reliability and quality/price. Yes I HAD a violet laser engraving amazingly well but the thing died, the manufacturer grant me a full refund.

I want to avoid spending money and waiting for products to arrive so then I run on chances to see how it works (I don't live on the USA so product delivery takes time). Sure, looking for reliability, no thanks, products of
US$ 2,000+ are not on my interest.
