Well, I finally broke down and ordered the G3.5 flight sim from Tower Sunday evening. It came lastnight while I was out, pretty quick service, I think. When I opened the box, I noticed they had sent me the G4 instead, the 3.5 was listed on the invoice. Just a bit confused, I called Tower this afternoon. They sent me a UPS label and told me the 3.5 would be sent out this evening. Not a big deal, just a simple mistake in the shipping department, just a slight hassle. I just could see hanging on to a more expensive item that I didn't pay for over an honest mistake. All in all, I think Tower has been quick and fair over this.
