the two cannot be compared the way you are asking.
im a strong supporter of dragonlasers.com they have superb customer service and every laser they sell is cherry picked and way overspec, just look at my viper in my signature!!! DL is a retail reseller of CNI laser products(see CNI banner ad at top of page). rayfoss also supposedly sells a few CNI lasers as well, but most are of unknown manufacturers(unknown to me anyways), i havent bought from rayfoss yet, and am hesitant to do so since there switch, the site just looks fishy to me. i would and always have recomended DL, however if $$ is an issue for you, talk to scopeguy20, he can get these same lasers cheaper through a group buy direct from CNI
hope this helps
I disagree Rayfoss has great customer support and Im pretty sure there a manufacturer. On the other hand Susie (O-like) was a bit rude to me when we talked and I have heard they may be a drop shipper.:cryyy:
Rayfoss has fantastic customer service. DL has higher quality lasers and is a bit more expensive, so I'd choose it over Rayfoss, which is cheaper, but still great.
