Jeff, sounds like you need to hit the ground running.

You are already ahead of the game on design, so you have a big advantage there, but the learning curve for SLA is a bit steeper/trickier than FDM. If you have already determined that 100 micron is going to be okay then forget about SLA printers (and especially the Wanhao D7, do not bother with it), and just look at FDM printers.

At 100 micron, you will have some leeway of being able to bump up/down a bit as well to get more detail when needed (most likely down to 50micron) at the expense of time, and you can go up to 200 micron and save time when you don't need as much detail. You will also find out that you can actually use multiple processes in Simplify3D and print at different layer settings, or use Slic3r and do essentially the same thing with the new variable layer height options. Things like foundations and base layers can be printed at lower resolution and then the software will increase the resolution when it gets to the building details. Neat stuff we have now.

Between the two you have listed, the Flashforge Creator Pro is a solid machine. A Prusa i3 MK2s is well within your budget and a superb machine, but only if you can buy from a local dealer, otherwise there is a bit of lead time on buying them online right now. Makerbots and Ultimakers are also good machines, albeit a bit pricey. This guide might help, but you've kind of already narrowed things down: https://www.3dhubs.com/best-3d-printer-guide

The klick-n-print could be a great machine, but two serious concerns 1) I have never heard of it. 2) That is such a massive price reduction, it appears they are dumping stock, and does not look like a new model is on deck.
