The A7 was pretty much always the best value in full-frame IMHO. I have not one single iota of regret being an early adopter at $1700 and under $1000 is just a ridiculous deal. I'm not surprised to hear that the new stock might finally be running out - it's had a good run...
Yes, definitely been a good run. I'm sure you've got your photography's worth out of it.
The sensor reflections have been a thorn in the side as has the somewhat workmanlike AF - I do look forward to upgrading away from both of those things eventually. But I'm not in a huge hurry; the build, interface and IQ are still very much to my liking.
Tradeoffs and workarounds

In what situations did you have issues with sensor reflections? What lenses in particular?
I liked the build in hand better than the A7II, which I just couldn't get myself to feel excited about. The A7 just felt right in my hands - the grip, weight, metal wheels, something subtle and intangible.
If you're anything like me, you may find yourself retiring your legacy optics once you get your hands on the newer lenses. But in the meantime, there are some fine results to be had - often blowing away crop formats IME - on a shoestring budget.
There are some old camera shops around that I now will go back to and scour, in fact I might do that later today. Any wide suggestions that do well on the A7 sensor you suggest?
Thanks!
