Unfortunately, I had a very bad experience with Modular CNC as well. They also go by the seller name of "cnc-empire" on eBay. I thought I had found a good company to get an inexpensive CNC mill from. After doing some research, I could not find any negative feedback about them or their machines. Unfortunately, every step of trying to get the mill from them was a hassle.
First, it took awhile for Andy, the owner, to provide me a quote. I tried to be patient, since he indicated that his wife was in the hospital. Email responses from him were too often slow and I had to send emails to at least two of his email addresses to make sure they got to him. I finally did get a quote on a partially assembled mill with a controller unit. The price seemed good, so I ordered one. I paid via PayPal, which turned out to be a mistake. It took nearly 6 weeks before the mill shipped, almost a week longer than promised. There was no communication that there would be any delay. Instead, Andy indicated that it had shipped on 4/28. However, the shipping label indicated that it really shipped on 4/30. That didn't sit well with me. What also didn't sit well was that he shipped it via USPS Parcel Post of all things. The tracking info for the machine was non-existent. It took an inordinate amount of time to arrive (was only going from NM to CO) and I had no idea where it was along the way. It took 10 days to arrive. By that time, I was absolutely fed up. I had no confidence in a product made by a company that is not able to run their business in a professional and honorable manner. Also, the shipping box looked Frankensteined together, which is not what I expect for a product costing $775.
I shipped the mill right back to him unopened and requested a refund. That was May 11. Here it is June 12 and he has yet to refund my money. First he claimed that he was having PayPal account problems and then later he said he was having cash flow issues. He promised to provide the refund by June 11, but has failed to live up to that promise. I have tried to be patient, but now I feel that I have been shafted. I am out over $825, when you factor in shipping costs. PayPal will not do anything, since it is past their 45 days to file a dispute. I was past that even before the machine shipped. I run a small company and because of this loss, I will likely have to cancel a planned business trip. I hope that my feedback will keep someone from making the same mistakes that I did.
Well, I still had the need for a CNC machine for my business, so I ordered a Zenbot 1216. That was on May 29. I received it on June 10 and started setting it up. Part of the gantry did suffer some shipping damage, but that company immediately shipped out a whole replacement gantry. Email responses have been prompt. Shipping was via UPS, so tracking info was readily available. It has been a night and day experience between the two companies. Zenbot has been much more professional, with good customer service and I feel far better that their machine will meet my needs.
