Mainly my issues are with reliability of supplying parts in the time they state they will. I've had several incidences of them charging for parts, and then not delivering because of no stock. Most of my issues have been resolved, but I know of others that are still way behind on their shipments. They also alter parts as they go and offer upgrades to some customers but not others. Communication is pretty poor and when some have raised concerns about it on their forums, they are either ignored or have post removed. Again, don't think I'm telling you not to buy this kit. Just make sure you're prepared and research before you commit. If you can dealcwith some shipping issues and really want the model, go for it. Their MF really is a nice kit for the most part.
