Some Simaddons airports lack the quality, IMO. For example, their CYEG has weird looking blue windows which looks nothing like the pictures I have seen of CYEG, as per my post here.
The worst part about Simaddons is, they charge so much for their airports. I really want a CYEG and CYYJ, even if I will use it temporarily, and if Simaddons charged a reasonable price, I would consider getting CYEG or CYYJ as a temporary add-on until a proper CYEG or CYYJ is done by FSimStudios, by you, etc.
But Simaddons does not charge a reasonable price, even though there is competition coming out (ie. FSimstudios will release their CYEG within weeks but Simaddons won’t budge on their price for CYEG). Personally, I bought the FSDreamTeam CYVR, even though I knew that FSimStudios was making CYVR. The FSDreamTeam CYVR was always a temporary stopgap until the FSimStudio CYVR. The reason with I bought the FSDreamTeam CYVR was because the price was reasonable, and the quality is actually quite good. While I no longer use the FSDreamTeam CYVR and I am using the FSimStudio CYVR, I don’t regret buying the FSDreamTeam CYVR one bit, because the price was reasonable at the time and the price was worth it for a “stop gap” temporary CYVR for me.
It’s too bad Simaddons charges what they do, for the quality that they have. If they had charged a more reasonable price for CYEG, 6 months ago, I would have considered getting that as a temporary stop gap until CYEG came out from FSimStudios. No way will I get CYEG from Simaddons with FSimStudios releasing their CYEG within weeks. And in the same token, no way will I buy CYYJ from Simaddons if you are working on CYYJ. Good luck with your CYYJ!
