They are legit. Whether you can handle it or want what they are offering is different, but you get what you pay for and we never had any surprises. I have gotten wild acros from the before and lots of live rock back when they had tons of it. We got Aussie and Marshall Island (I think) acropora - a few were amazing, most were good and a few were just OK. This happens with every shipment. We paid more not to get any pseudo acros like cyphasterea or leptos and no montis. We asked for a good amount of smooth skins, millepora and spaths and they did a good job of getting us a good amount. You also have to be able to land and host these things. I do not dip them right away and wait for them to heal and recover, but I have a spare tank just for them so pests are no issue.
The only thing that you don't know up front is the freight shipping from LAX to your local airport, but you can get a close estimate. I cannot remember if it was Southwest or American, but it could have been both. You also don't know for sure when your shipment is coming and we got one in 3-4 days and another in 3-4 weeks - this is where it helps to have more than one hobbyist in case your kid has a birthday when the flight is landing (ask me how I know).
They will sell to you. They were always honest and upfront with me.
If you want to have an idea of what you might get, go to Divers Den and look at the wild acropora colony section. Keep in mind that this is what is left over after the high dollar players, employees, etc. have picked over the great stuff... so this is kinda your floor.
You can also get mari boxes. These usually have higher success rate and are selected to be more adaptable for aquarium life.
If you order, millepora, plana, shortcakes (microclados), tables (hycanithcus) do not let people down that often. Plana usually come in multiple colors and are undervalued right now, IMO. True Torts and Austera also have high floors for coloring. People love the super awesome tenuis right now, but you can bet that for every one of those, about 9 other dull ones were imported... so these are risky to select blind.
I cannot stress enough that trans shipping and wild colony boxes are not for everyone. You will have losses that you have to eat the cost of. You also will have to deal with usually having a separate system to host them at first. Then, you have to deal with getting rid of the ones that you don't want later - don' t expect to get retail for them since you are not a store. If you can handle it, it is really great. If not, then it can suck.
