Which Reflex package do I buy?

[racin06]

I own a DX7 Tx. Which Reflex package do I buy at the below link? Also, what is the difference between Reflex Flight Simulator ($139.99) and Reflex XTR ($199.99)? Thanks:

It's not really clear what they are selling. Reflex is at a strange point right now. Up to version 5.03 uses the old dongle and costs about $130 - 140. If you get this version, there will not be any more upgrades to support this dongle. Version 5.04 uses a new dongle and will be supported with future upgrades. 5.04 appears to go for $200+. Uogrades from 5.03 to 5.04 are available if you return your dongle plus 75 euros. The reason for the change was hacked dongles selling for cheap, as you can get the software free.

That said, 5.03 works fine, and with the JR cable will work fine with your DX7. I'm currently using a DX6, will shortly upgrade to the 7.
