I'm with Twobob, why do you need this co. to help you find a property? Are you not confident in your own research?
Remember, a lot of these co's (I don't know this one specifically) have deals with developers to sell their projects - which is why they're always new properties and units. You may also be paying more than comparable sales elsewhere because if they offer you a no fee service, they will obviously be getting a nice commission from the developer who may need to build that into the sale price.
