I just bought a T-9 and a T-10 from Founders, having used a taxi to get over there (in the spirit of what I was buying I used an AspS 
)
I kitted out both, flew the T-10 back home & once there had the T-9 shipped over. It cost 400k to ship and took ~12mins, and paid for the shipping cost in a single cargo run. I spent the time testing the T-10 (never had one before) and looking at it with the camera, I could have done a few other missions & the T-9 would just have been waiting when I returned, it wasn't a big deal.
I could have flown back in another taxi to collect the T-9, and it would have been more of a chore, both the cost and time were pretty well spot on believable. I don't think anything needs to be changed.
