I think I am going to take back all I have said to encourage people to buy a Rift (or Vive). This is getting darned expensive!
Since getting the Rift at the end of April, I have added the following to my DCS hangar: M2000C, L39, Mig 15, Mig 21 and tonight I pulled the trigger on the Gazelle. I also want the F5E but that might have to wait until my birthday. On top of that I also picked up Aerofly FS 2 and the Switzerland DLC, oh, and the Museum Relic campaign.
Yep, had to have the F5E. Sigh. Fortunately that is the last module I am interested in at present. It also means that I am pretty much caught up, so I should only need to purchase one module at a time as they are released from this point forward.
